We want to know how long it's actually taking to process asynchronous
contact/host deletions and DNS refreshes on host renames. This adds
instrumentation. Five metrics are recorded as follows:
* An incrementable metric for each async task processed (split out by
type of task and result).
* Two event metrics for processing time between when a task is enqueued
and when it is processed -- tracked separately for contact/host
deletion and DNS refresh on host rename.
* Two event metrics for batch size every time the two mapreduces are
run (this is usually 0). Tracked separately for contact/host deletion
and DNS refresh on host rename.

The StatusProhibitsOperationException superclass constructor just wants a raw message to return to the client, so we should pass it an explanation rather than just the superordinate domain name. In fact, I think the superordinate domain name isn't really necessary since it should be obvious from the hostname in the create/update request what the superordinate domain would be.

We now send PendingActionNotificationResponses in our poll messages upon completion of an asynchronous contact or host deletion. This is part 1 of 2, which begins logging Trid in all enqueued Host/Contact deletion flows for use in batch deletions, and optionally consuming the resultant Trid info to emit a Host/ContactPendingActionNotifcationResponse.
Part 2 will make this response emission non-optional, which will happen once the queue is cleared of all non-Trid containing tasks.

As part of b/36599833, this makes FlowRunner log the appropriate ICANN activity
report field name for each flow it runs as part of a structured JSON log
statement which can be parsed to generate ICANN activity reports (under the key
"icannActivityReportField").
In order to support this, we introduce an annotation for Flow classes called
@ReportingSpec and a corresponding enum of values for this annotation, which is
IcannReportingTypes.ActivityReportField, that stores the mapping of constant
enum values to field names.
The mapping from flows to fields is fairly obvious, with three exceptions:
- Application flows are all accounted under domains, since applications are
technically just deferred domain creates within the EPP protocol
- ClaimsCheckFlow is counted as a domain check
- DomainAllocateFlow is counted as a domain create
In addition, I've added tests to all the corresponding flows that we are
indeed logging what we expect.
We'll also need to log the TLD for this to be useful, but I'm doing that in a
follow-up CL.

EPP host spec section 3.2.5 requires that attempts to update hosts that are linked to different registrars must fail with error code 2305. This is complicated to do, as linked status is eventually consistent, and even more painful when checking links to those of different registrars.
This change forbids external-to-anything renames entirely.

In fact, completely eviscerate cloneProjectedAtTime (to be removed in
a followup CL) in favor of doing the projection of transfers and the
loading of values from the superordinate domain at call sites. This
is one of the issues that blocked the memcache audit work, since the
load inside of cloneProjectedAtTime could not be controlled by the
caller.
Note: fixed a minor bug where a subordinate host created after its superordinate domain was last transferred should have lastTransferTime==null but was previously reporting the domain's lastTransferTime.

All domain/host names should be stored in their canonical forms (puny-
coded and lower-cased). This validation is already in the flows, but
this adds protection against bad data from other sources, e.g. admin
consoles or RDE imports.
This also removes an old work-around that temporarily suspended this
validation for superusers, because we used to have non-canonicalized
data in the system. The non-canonicalized data has since all been
cleaned up, so this work-around is no longer necessary.

This bug is about a bad use of Optional.
We were checking == null instead of .isPresent(), so the check
always passed, and we always set a lastSubordinateTime when
updating hosts, even if the host was external and should have
had a null value in that field.
There is almost certainly bad data in prod in the sense
that any external host that was ever updated will have a value
for this field instead of null. However, this is not
consequential as the field is entirely meaningless for
external hosts, and will be properly reset if the host is
ever moved to be internal.

LINKED is supposed to be a virtual status that gets added/removed
when needed. It's mistakenly been persisted to datastore on many
resources, but the persisted value is meaningless and may not
represent reality at all. There is no reason to check for LINKED
status before kicking off a delete, since the smoke test and
[] will catch all actual linked objects, and the LINKED
status can be causing false positives for objects that are no
longer LINKED.

This is probably best from a code-cleanliness perspective anyways,
but the rationale is that tightly coupling the resources to the
info responses was a straightjacket that required all status
values and fields to be directly available on the resource. With
this change, I already was able to get rid of the preMarshal()
hackery, and I will be able to get rid of cloneWithLinkedStatus()
and most of the contents of cloneProjectedAtTime() for non-domains.

This is the final preparatory step necessary in order to load and load
configuration from YAML in a static context and then provide it either via
Dagger (using ConfigModule) or through RegistryConfig's existing static
functions.

This is the first in a decently long series of commits to delete RegistryConfig
entirely and centralize all configuration in ConfigModule using Dagger. Once
this is done, then the text-based YAML configuration work can begin in earnest.
Note that the configuration settings from TestRegistryConfig will be moving
into ConfigModule.LocalTestConfig. This way they can be referred to in a static
context from test and test utility helpers, rather than having to be injected
everywhere, which we don't typically bother with for tests.

This should have been getting turned into an InvalidHostNameException, but
wasn't. I've added tests for HostFlowUtils verifying the correct behavior for
this. Idn.toASCII() can throw IllegalArgumentException for some combinations
of input, including hostnames with a leading hyphen, so the call should be
inside the try block that turns IAEs into InvalidHostNameExceptions.

This now throws errors when a non-lower-cased, non-puny-coded, or non-canonicalized host name is passed in as an input parameter.
The approach we'll take is to first notify registrars which hosts we'll be renaming, then
issue EPP host update commands to effect those renames as superuser, then push this code
live to production.
This fixes#38 on GitHub.

This allows handling of N asynchronous deletion requests simultaneously instead
of just 1. An accumulation pull queue is used for deletion requests, and the
async deletion [] is now fired off whenever that pull queue isn't empty,
and processes many tasks at once. This doesn't particularly take more time,
because the bulk of the cost of the async delete operation is simply iterating
over all DomainBases (which has to happen regardless of how many contacts and
hosts are being deleted).

This change replaces all Ref objects in the code with Key objects. These are
stored in datastore as the same object (raw datastore keys), so this is not
a model change.
Our best practices doc says to use Keys not Refs because:
* The .get() method obscures what's actually going on
- Much harder to visually audit the code for datastore loads
- Hard to distinguish Ref<T> get()'s from Optional get()'s and Supplier get()'s
* Implicit ofy().load() offers much less control
- Antipattern for ultimate goal of making Ofy injectable
- Can't control cache use or batch loading without making ofy() explicit anyway
* Serialization behavior is surprising and could be quite dangerous/incorrect
- Can lead to serialization errors. If it actually worked "as intended",
it would lead to a Ref<> on a serialized object being replaced upon
deserialization with a stale copy of the old value, which could potentially
break all kinds of transactional expectations
* Having both Ref<T> and Key<T> introduces extra boilerplate everywhere
- E.g. helper methods all need to have Ref and Key overloads, or you need to
call .key() to get the Key<T> for every Ref<T> you want to pass in
- Creating a Ref<T> is more cumbersome, since it doesn't have all the create()
overloads that Key<T> has, only create(Key<T>) and create(Entity) - no way to
create directly from kind+ID/name, raw Key, websafe key string, etc.
(Note that Refs are treated specially by Objectify's @Load method and Keys are not;
we don't use that feature, but it is the one advantage Refs have over Keys.)
The direct impetus for this change is that I am trying to audit our use of memcache,
and the implicit .get() calls to datastore were making that very hard.

ReferenceUnion is a hack to work around the mismatch between how
we store references (by roid) and how they are represented in EPP
(by foreign key). If it ever needed to exist (not entirely clear...)
it should have remained tightly scoped within the domain commands
and resources. Instead it has leaked everywhere in the project,
causing lots of boilerplate. This CL hides all of that behind
standard Refs, and should be followed by work to remove ReferenceUnion
completely.

The dark lord Gosling designed the Java package naming system so that
ownership flows from the DNS system. Since we own the domain name
registry.google, it seems only appropriate that we should use
google.registry as our package name.
This change renames directories in preparation for the great package
rename. The repository is now in a broken state because the code
itself hasn't been updated. However this should ensure that git
correctly preserves history for each file.
