Specifically:
- remove @RequestScope from EppMetric since it's only for components
- fix to call the better overload of toBigqueryTimestamp
- use the same UUID provider for BigQueryMetricsEnqueuer that already exists for
the VerifyEntityIntegrityStreamer
- minor cleanup in VerifyEntityIntegrityStreamer (inject projectId vs whole env)

Getting rid of builder boilerplate makes my heart sing. Since we can no
longer @Inject the Builder() constructor, this change adds a provider
in WhiteboxModule that calls a special builderForRequest() factory method,
which gets passed a request ID and Clock and preserves the existing
EppMetric magic that sets the start and end time for you.

The latter is the canonical way to call it; the former is not available in

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.

This is one of a series of CLs which will refactor EppMetrics into a value type
and Metrics into a stateless class which will have an export(EppMetrics requestDetails)
method to export EPP metrics in a stateless way. Once EppMetrics is a value
type, I will create a new StackdriverEppMetrics that will also accept the value
type via an incrementRequests(EppMetrics requestDetails), allowing us to
monitor EPP via BigQuery and Stackdriver with minimum code duplication.

This CL also adds IncrementableMetric#reset() methods to allow resetting the
value and start timestamp of IncrementableMetrics.
This is necessary because some backends, like Stackdriver, use non-monotonic
changes in cumulative metric values to detect timeseries restarts. Tracking and
re-setting the start timestamp allows users to track mostly monotonic metrics
which may have non-monotonic discontinuities.
See https://cloud.google.com/monitoring/api/ref_v3/rest/v3/TimeSeries#Point for
more details.

This change enforces that IncrementableMetrics should only monotonically
increase in value, and adds a new increment() method to increment by one, which is slightly faster than incrementBy (due to a lack of non-negative checking) in the common case that the counter should only be incremented by one.

This adds Stackdriver as a DI module into the registry codebase. This is a
necessary prerequisite for using Stackdriver based monitoring. For now, I'm
only adding it to the backend module as it will be more work to add it to the

This introduces Actions and Dagger up until FlowRunner. The changes
to the servlets are relatively simple, but the required changes to
the tests, as well as to auxillary EPP endpoints (such as the http
check api and the load test servlet) were vast. I've added some
comments in critique to make the review easier that don't really
make sense as in-code comments for the future.

Old ForeignKeyIndex entities pointing to hosts are soft-deleted when a
host is renamed, and a new ForeignKeyIndex is created that correctly
points at the new host. This is an expected state of the system, so
don't throw an error when it is observed.

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.

There are several situations in which it is a valid system state for
Keys to PollMessages on Domains to point to entities that don't exist,
chief amongst them when a domain has been soft-deleted. We also can't
simply null this out when soft-deleting domains, because there may be
an un-acked recurrence meaning it can't be deleted.
Given this, it doesn't make sense to check for entity existence here,
as it is not a system invariant and cannot easily be made to be so.

This refactors the existing premium list functionality into the new
class StaticPremiumListPricingEngine, which implements PricingEngine.
A backfill @OnLoad is provided to default existing Registry entities
into the static implementation. For now there is just this one
implementation. Dagger map multibinding is used to generate the total
set of allowed pricing engines, and allows other parties to plug in
their own implementations.
The pricing engine is a required field on the Registry object. If you
don't want a particular Registry to actually have a premium list, then
use the static pricing engine but don't actually set a premium list.
A subsequent CL will refactor the Key<PremiumList> field on the
Registry entity class to be handled solely by the
StaticPremiumListPricingEngine implementation. Going forward, all
configuration and implementation details that are specific to a given
pricing engine should be handled by that pricing engine, and not as
fields on the Registry object.

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.
