Remove mysql server_id cherry-pick

This already merged upstream and our LKG commit includes it, which
causes the cherry-pick to fail.
Add cherry_pick function

We've hit a number of issues with upstream patches merging and
breaking our cherry picks.  This adds a variation on the upstream
CI cherrypick function that will log failures instead of killing
the entire run.  This should still allow us to easily find old
cherry picks that can be removed, but makes the whole process less
error-prone.  It also means we don't have to worry about a cherry
pick working with LKG and not with master because it merged after
LKG was set.
Fix diskimage-builder cherry-pick

Forgot to commit this before I pushed.
Set distro correctly for rhel7

We were still configuring the elements for fedora even when using
the rhel7 json file, which caused some necessary elements to be
missed.
