This ensures that only one will run at a time, which should help fix the
clogged up mapreduces we've seen on sandbox.
In order to do this, the UnlockerOutput is introduced. This unlocks the
given Lock after all reducer shards have finished.
Also increases the lease duration of the DNS refresh action from 20 to
240 minutes. 20 minutes isn't long enough; when there's a lot of domains
and decent system load the mapreduce could take longer than that in the
ordinary case.
TESTED=Deployed to alpha and verified that more than one copy of the
mapreduce wouldn't run simultaneously, and also that the lock is
released when the mapreduce is finished.

This is a 'green' Flogger migration CL. Green CLs are intended to be as
safe as possible and should be easy to review and submit.
No changes should be necessary to the code itself prior to submission,
but small changes to BUILD files may be required.
Changes within files are completely independent of each other, so this CL
can be safely split up for review using tools such as Rosie.

This is a 'yellow' Flogger migration CL. Yellow CLs should be mostly safe
but include changes that are notable for one reason or another. Manual
intervention may be required to address small issues.
The comments in this CL indicate cases where suggested code changes
should be double checked, or even modified. There may even be cases where
files outside this CL are affected by changes to things such as logger
visibility. However if a change does not have an associated comment then
it should be safe.

Datastore has a non-zero chance of failing on reads. A map-reduce with too many
failures will eventually give up. As a result, any map-reduce that goes over a
large number of datastore entities is almost guaranteed to fail.
Since we expect to have a large number of EppResources, we make sure to wrap
all datastore reads with some retrying mechanism to reduce the number of
transient failures that propagate to Map-Reduce.
This feature already existed for CommitLogManifestReader, we refactor the code to use the same retrying mechanism in EppResource readers.
Also removed the transactNew around the reads because looking at the source - it doesn't actually do anything we need (doesn't retry on any failure other than concurrency failure)

'afterFinalFailure' is called just before rethrowing a non-retrying error from
the retrier. This can happen either because the exception shouldn't be retried,
or because we exceeded the maximum number of retries.
The same thing can be done by catching that thrown error outside of the
retrier:
retrier.callWithRetry(
callable,
new FailureReporter() {
@Override
void afterFinalFailure(Throwable thrown, int failures) {
// do something with thrown
}
},
RetriableException.class);
is (almost) the same as:
try {
retrier.callWithRetry(callable, RetriableException.class);
} catch (Throwable thrown) {
// do something with thrown
throw thrown;
}
("almost" because the retrier might wrap the Throwable in a RuntimeException,
so you might need to getCause or getRootCause. Also - there is the
"beforeRetry" I ignored for the example)
Removing "afterFinalFailure" also makes the FailureReporter in line with Java 8
functional interface - meaning we can more easily create it when we do need to
override "beforeRetry".

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.

When trying to run the MapReduce for DeleteOldCommitLogsAction, we run into a
lot of DatastoreTimeoutException during CommitLogManifestReader.next.
This causes the entire shard to fail. Since we have a lot of keys (tens of
millions), this is almost guaranteed to happen, dooming the entire MapReduce.
Here is an attempt to recover from the Timeout Exception by saving the state
before the read, then on failure restoring that state and trying again.

Attempting to run DeleteOldCommitLogs in prod resulted in a lot of DatastoreTimeoutException errors. The assumption is that attempting to load so many CommitLogManifests (over 200 million of them), when each one has a slight possibility of failure, has a very high probability of error.
The shard aborts after 20 of these errors, and by eliminating as many loads as possible and retrying the remaining loads inside a transaction we are effectively eliminating any exceptions "leaking" out to the mapreduce framework, which will hopefully keep us bellow 20. At least, that's our best guess currently as to why the mapreduce fails.
EppResources are loaded in the map stage to get the revisions, and CommitLogManifests are only loaded in the reduce stage for sanity check so we don't accidentally delete resources we need in prod. Both of these are wrapped in transactNew to make sure they retry individually.
The only "load" not done inside a transaction is the EppResourceIndex, but there's no getting around that without rewriting the EppResourceInputs.

We're now using java_import_external instead of maven_jar. This allows
us to specify the relationships between jars, thereby allowing us to
eliminate scores of vendor BUILD files that did nothing but re-export
@foo//jar targets, thus addressing the concerns of djhworld on Hacker

We now have redundant failover mirrors, which is a feature I added to
Bazel 0.4.2 in ed7ced0018
A new standard naming convention is now being used for all Maven repos.
Those names are calculated from the group_artifact name using the
following algorithm that eliminates redundancy:

The JSR330 dep has been removed from java targets if they also depend
on Dagger, since Dagger always exports JSR330.
Annotation processor dependencies should now be leaner and meaner, by
more appropriately managing what needs to be on the classpath at
runtime. This should trim down the production jar by >1MB. As it stands
currently in the open source world:
- backend_jar_deploy.jar: 50MB
- frontend_jar_deploy.jar: 30MB
- tools_jar_deploy.jar: 45MB

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.

We've continuously had concurrent modification exceptions for our regularly
occurring []s that run on thousands of shards, perhaps unnecessarily so.
These exceptions started after the last major [] framework refactoring,
which changed the default number of shards from 100 to essentially infinite. I
don't think infinite is the way to go, and 100 shards should be more than
sufficient for anything we're currently running.

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.
