After investigating common domain create/update command usage
patterns by registrars, we noticed that it is frequent for a
given registrar to reuse both hosts (using a standardized set of
nameservers) as well as contacts (e.g. for privacy/proxy
services). With these usage patterns, potential per-registrar
throughput during high volume scenarios (i.e. first moments of
General Availability) suffers from hitting hot keys in Datastore.
The solution, implemented in this CL, is to add short-term
in-memory caching for contacts and hosts, analogous to how we are
already caching Registry and Registrar entities. These new
cached paths are only used inside domain flows to determine
existence and deleted/pending delete status of contacts and
hosts. This is a potential loss of transactional consistency, but
in practice it's hard to imagine this having negative effects, as
contacts or hosts that are in use cannot be deleted, and caching
would primarily affect widely used contacts and hosts.
Note that this caching can be turned on or off through a
configuration option, and by default would be off. We'd only want
it on when we really needed it, i.e. during a big launch.

This removes some qualifiers that aren't necessary (e.g. public/abstract on interfaces, private on enum constructors, final on private methods, static on nested interfaces/enums), uses Java 8 lambdas and features where that's an improvement

This was a surprisingly involved change. Some of the difficulties included
java.util.Optional purposely not being Serializable (so I had to move a
few Optionals in mapreduce classes to @Nullable) and having to add the Truth
Java8 extension library for assertion support.

This was needed to correct bad data (LINKED status values on EppResources). The code has been fixed to no longer persist LINKED on any resources and I ran a resave all action yesterday to remove all persisted LINKED status values, so the migration @OnLoad can be safely removed now.

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.

This generalizes the "LINKED can't be anywhere" idea into more
targeted restrictions.

* Remove LINKED when loading an EppResource
* Enforce that you can't add it to a resource
* Ignore LINKED on xjc import of contacts and hosts
After running ResaveAllEppResourcesAction we will no
longer have persisted LINKED statuses in datastore.
In the process of writing this I discovered that RDAP
treats LINKED like any other status value and returns
the persisted value rather than the derived one. Since
this is an existing bug and is orthogonal to the changes
in this CL, I am addressing it in a separate CL.

This was used in DomainInfoFlow to return a DomainResource with no
nameservers without making INACTIVE show up. It was nominally used
in DomainApplicationInfoFlow for the same reason, but that's just
an artifact of the old flow hierarchy since applications never have
INACTIVE set anyways. In either case, now that we have the DomainInfo
return object instead of returning DomainResource directly from the
flow, it's better handled within the flow.

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.

and HostResource.
DomainApplication is not transferable and has no need for this
field. HostResource needs it because it can be transferred with
a domain.
This is all in service of removing the ofy().load() inside of
host's cloneProjectedAtTime.

HostResource and DomainApplication are not transferable, (or at
least, not directly in the case of hosts) and have no need for
the TransferData field. In a flat-flow world, we can push it down
to where it's actually used.

Although the delta implies that this is actually adding code, it's
better than it looks, because some of the stuff in ContactFlowUtils
is duplicating more generic methods in ResourceFlowUtils, which
can be deleted when the domain and host flows are cut over.

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.

XjcToContactResourceConverter is, as it name suggests, an inverse of
ContactResourceToXjcConverter. This utility class is designed to

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.
