[swarming] fix frontend / backend split

There is a memory leak issue, and I'm starting with reducing the number
of variables by properly splitting the apps.

- Removes an old /internal/.+ redirect on the frontend module to the
  backend handlers.
- Improve comments in app.yaml and module-backend.yaml

[components] reorder utils.py

No functional change. Only code moved around.

I want to add new code, but I felt this file was due for a reordering
first. The new code will be in Handler section.

[swarming] Report memory usage after each handler

Add this to config service too.

This will help diagnose leaks as I'll be able to look at all log for one
specific GAE instance and see the difference in memory usage across
requests.

I will need to add it to gae_ts_mon too, but I'll need to tweak upstream
first.

Fix a small error in d63fdb9a27d0e89

The hook for memory usage must be disabled in unit tests, not when running in
the dev server.

[gae_ts_mon] report memory usage if it increased significantly

I suspect this may be causing issues. We'll have to traces to determine
if so.
