Revert of ts_mon: remove dependency on apiclient.

Revert of ts_mon: remove dependency on apiclient. (patchset #2 id:20001 of https://codereview.chromium.org/1588623002/ )

Reason for revert:
This broke chromium_try_flakes. I am not sure why, but after this change I get an error on importing six from gae_ts_mon. Possibly this is because there is another version of six in appengine/third_party.

time tested on an actual app, end-to-end.
