[isolate] Add new prpc service to retrieve statistics

- This adds back a way to extract statistics from the Isolated server. This had
  to be removed years ago due to security issues.
- This should enable re-creating a Web UI for the statistics dashboard.
- I decided to use prpc to see if it can be used fine in case I want to switch
  the Swarming server to prpc. Using protos is generally better for readability
  for users than 'protorpc', which is completely unmaintained. I decided to do
  it here because the code is very simple, yet the same flow could be used for
  Swarming Web UI.
- Tweak stats_framework to be nicer to use.

[isolate] call out that I know the API needs to be completed

So it doesn't look like an half-hearted attempt.

[isolate] Tweak isolated.proto

- Add version number to the package, I hadn't realized it was possible.
  This will help future-proofing the service.
- Since this is a breaking change, use this occasion to tweak some of
  the protos members.
- Add documentation to the proto.
- Backport improvements from ../swarming/setup_bigquery.sh. Eventually
  the script will be generalized, but not yet. :)

Deployment of this code will be annoying, as I need to recreate the BigQuery
tables from scratch.

Usage is now:

  echo '{"resolution":"MINUTE","page_size":20}' | \
    prpc call <host> isolated.v1.Isolated.Stats

Revert "[isolate] Temporarily disable send_to_bq cron job"

This reverts commit 1492a840f2d79137d0513d737b0bdcdf2a6febc6.

Reason for revert: Instance cleanup is completed

- I uploaded the version to all instances, disabling the cron job
- I made it the default, ensuring the default version had good code
- I deleted the entity BqStateStats
- I cleared memcache (and tweaked settings for some instances)
