Apply Issue shim for disabling checkout when bot update ran.

Apply Issue changes for disabling checkout when bot update ran.

This add --force to ignore the flag file.
This also passes --base_ref so we can specify which ref we're basing off of so that it does not incorrectly assert that it is basing off origin/master

Apply issue is out of the normal gclient master step.

Looks right, but make sure the message is the same as in the other steps. LGTM.

Ptal again.  Added a bypass flag along with a --base_ref flag which would be
needed by https://codereview.chromium.org/170843003/

Message was copypasta from another script.
