ModulesService does not provide a great API. Specifically, it doesn't have a
way to get the hostname for a specific service; you have to get the hostname for
a specific version as well. This is very rarely what we want, as we publish new
versions every week and don't expect old ones to hang around for very long, so
a task should execute against whatever the live version is, not whatever the
current version was back when the task was enqueued (especially because that
version might be deleted by now).
This new and improved wrapper API removes the confusion and plays better with
dependency injection to boot. We can also fold in other methods having to do
with App Engine services, whereas ModulesService was quite limited in scope.
This also has the side effect of fixing ResaveEntityAction, which is
currently broken because the tasks it's enqueuing to execute up to 30 days in
the future have the version hard-coded into the hostname, and we typically
delete old versions sooner than that.

Async tasks will now re-enqueue themselves after completion if there are
additional pending future actions. This allows all parts of domain delete flows
to be successfully re-saved as the parts happen, without going past the maximum
allowed 30 day task ETA limit. The first task runs at 30 days out when the
redemption grace period ends, and that task then enqueues another task to run 5
more days in the future, when the deletion is final and the pending delete
status gets removed.
No data migration plan is necessary because future resaves defaults to empty,
and indeed will always be empty on transfers. So previously enqueued tasks will
still be valid.

This is used in the domain transfer and delete flows, both of which are
asynchronous flows that have implicit default actions that will be taken at some
point in the future. This CL adds scheduled re-saves to take place soon after
those default actions would become effective, so that they can be re-saved
quickly if so.
Unfortunately the redemption grace period on our TLDs is 35 days, which exceeds
the 30 day maximum task ETA in App Engine, so these won't actually fire. That's
fine though; the deletion is actually effective as of 5 days, and this is just
removing the grace period.
