The higher the number the better for serious launches. These used to be 100
but had been detuned because instances weren't dying correctly when no longer
needed, thus contributing to higher costs than necessary. That problem was
fixed when we migrated to the Java 8 runtime, however, so there's no reason
not to use the higher number.

There are 2 types of changed done here:
- reorder the existing cron jobs to be in the same order as production (for
easier diffing)
- add missing cron-jobs to either alpha or sandbox

That's 50 each for frontend and backend and 5 for tools. Since the
MetricExporter bug has been fixed for awhile now, we aren't gaining anything by
artificially keeping the instance number low, whereas we might benefit from
higher instance counts, e.g. for load-testing.

Loadtesting data is identified as "prober data" by this job (it removes
anything under ".test", not only prober data)

This should help reduce the occurrence of requests taking a long time
to process because a new instance is being spun up. We might consider
increasing this further to 60 minutes in the future if necessary.
This also increases the number of frontend instances on production to 8
from 6, since it appears like the issue we were attempting to mitigate
with that change is now fixed.

It makes sense for all mapreduces to run in backend, especially onces
that are scheduled regularly to run in cron like this one now. We don't
have many instances configured for the tools service anymore on some
of our environments, so backend is the friendliest place for a mapreduce
to run.

Also adds a "resave all epp" cron job that's needed for the delete to work correctly.

My continuing investigations into necessary resources for running
our environments seems to indicate that four instances should be
sufficient for our purposes. If it's not, we can always revert.

We want to lower the maximum number of service instances as much as
possible without affecting service reliability so that we can make
stronger statements about what the maximum cost of running a typical
Nomulus environment might be. This first step likely won't affect the
frontend and tools modules in practice because they aren't typically
running even this many instances, but it will clamp down on the
number of backend instances (which should be fine; it just means the
mapreduces will take longer).
Alpha is tuned down the same as sandbox for consistency reasons.
This also standardizes on the B4 size (which has 512 MiB RAM) for
all instances. Most instances were already using this, and the
deviations from it were seemingly at random. Crucially, backend,
which is likely most sensitive to this because it uses the mapreduce
library, is already on the smaller memory size.

The YAML configuration files are now being built directly into the
JAR, and not stored in the WEB-INF/ directory, so this is unnecessary.

This implements the basic framework that allows global YAML
configuration, per-environment custom configuration, and unit-
test-specific configuration.
TESTED=I deployed to alpha, ran some EPP commands through the
nomulus tool, and verified no errors.

Note that this merely starts this MR on a daily schedule -- the billing queries that ultimately consume the synthetic OneTime events are filtering out the events at this time, so we're still relying on query-time expansion of Recurrings.

App Engine provides a servlet which deletes up to 100 expired _ah_SESSION entities from DataStore. This CL adds a cron job to call the servlet every 15 minutes in both alpha and sandbox. Assuming all goes well, we will turn it on in production.
I originally learned about this servlet here:
http://www.radomirml.com/blog/2011/03/26/cleaning-up-expired-sessions-from-app-engine-datastore/
But it appears that we do not need a servlet definition, just a cron entry.

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.

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).

This is the first step in consolidating our task queues down into a smaller
number. We have lots of tasks that run quite infrequently, and they can all run
in the same queue to get retry semantics without needing a new queue for each
cron entry.

These build rules allow Bazel to generate the .ear and .war files which
appcfg.sh (a tool that comes with the App Engine SDK) can then use to
perform a deployment.
Included in this CL are configurations for five separate production
environments: production, sandbox, alpha, crash, and local.
