Runnable and Callable are both @FunctionalInterfaces. The difference is
that Callable requires a return value whereas Runnable does not, so in
situations where we don't care about a return value, rather than having to
add an unnecessary 'return null;' at the end of the lambda, we can simply
use a non-returning Runnable instead.
Unfortunately, owing to legacy reasons, Runnable is not declared to throw
checked exceptions whereas Callable is, so in situations where checked
exceptions are thrown we still need to have a 'return null;' call at the
end.

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.

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.

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.

We should be able to remove the dependency on the App Engine [] library from the frontend service, since no []s actually run there. In order to do this, we need to remove the various []-reliant classes from the frontend service build. This CL begins the process by moving the two async "flows" to a different package which is not included in the frontend service.

TESTED=I deployed it on alpha, renamed some hosts, and verified that
the [] ran as expected.

This will replace the existing DnsRefreshForHostRenameAction.
This is stage one of a three stage migration process. It adds the new queue and
[] but doesn't call them yet. Stage two will cut over to using the new
functionality, and stage three will remove the old functionality.

Also consolidates the DNS refresh functionality in AsyncFlowUtils that was
being used by HostUpdateFlow into AsyncFlowEnqueuer.
TESTED=I threw together some batch scripts to create dozens of contacts on
alpha and then request their deletion, and the [] ran fine and
successfully deleted them in batches.

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).
