This is in preparation for running the automatic refactoring script that
will replace all ExpectedExceptions with use of JUnit 4.13's assertThrows/
expectThrows.
Note that I have recorded the callsites of assertions about EppExceptions
being marshallable and will edit those specific assertions back in after
running the automatic refactoring script (which do not understand these).

The only remaining methods on ExceptionRule after this are methods that
also exist on ExpectedException, which will allow us to, in the next CL,
swap out the one for the other and then run the automated refactoring to
turn it all into assertThrows/expectThrows.
Note that there were some assertions about root causes that couldn't
easily be turned into ExpectedException invocations, so I simply
converted them directly to usages of assertThrows/expectThrows.

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.

We can easily end up enlisting too many entity groups (separate
DomainApplications) in a TransactionalFlow when loading all applications
tracked by the DomainApplicationIndex. This makes the load operation
transactionless, to avoid overenlisting.
Potential problems:
1. We fail to prevent landrush applications, if a single sunrise application
exists. This is likely fine, except for a brief moment in Sunrush when a
sunrise application is made immediately prior to a landrush application. The
result is we accept an invalid application- which can be mediated manually.
2. We fail to prevent a domain create for a domain with an open application.
This is a little more sinister, but also unlikely unless someone submits an
application immediately before someone tries to create the same domain (sans
application?)
3. We return an invalid DomainCheck response (instead of 'pending allocation').
Not the worst outcome.
4. We reduce the AuctionStatusCommand and GetApplicationIdsCommand to
eventual consistency. Since they're internal tools, that's not too big a deal.
A better solution:
DomainApplications really should just be normalized under a virtualEntityGroup
by fullyQualifiedDomainName, or a hash-bucket like EppResources are. The
DomainApplication -> DomainBase -> EppResource hierarchy seems to be purely for
code reuse, at the cost of Datastore consistency. This would, however, require
quite some refactoring, and a custom resave operation across all
DomainApplications.

The next step will be to get rid of RegistryConfig descendants and RegistryConfigLoader entirely.

Almost all uses were in test classes, which I replaced with clock.nowUTC().

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.

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.
