[swarming] Mark many functions in lease_management as private

It's a very deep rabbit hole but the end goal is to refactor
handlers_backend.py, even if it doesn't look like it.

No functional change.

[swarming] Further refactor lease_management.py

This is actually in preparation to cleanup handlers_backend.py, but the
rabbit hole went deep.

- Mark more functions not used outside the file as private.
- Add cron_ or task_ prefix to functions as relevant and tidy
  handlers_backend.py a bit.

I struggled *a lot* making this CL because if I add 'from server import config'
inside lease_management.py, there's a unit test that fails. I haven't searched
as to why, I've made handlers_backend pass the necessary value to
cron_sync_config() instead.

No functional change.

[swarming] group public code together in lease_management.py

That's my last CL to refactor this file.

No code modification, it's only move around untouched.

[swarming] Cleanup handlers_backend.py

- Move logic from cron jobs out of handlers_backend into the relevant files as a
  standalone function.
- Create a base class _CronHandlerBase to reduce repetition.
- Remove the 'Success' output, it's useless.
