Use Bug: footer for Gerrit CLs

Note that because it is now a gerrit footer, it both appears in the same block
as the Change-Id footer (no blank line between them), and isn't guaranteed to be
above the Change-Id footer. This doesn't matter during "git cl upload", when
a Change-Id hasn't been allocated yet, but will show up during "git cl
description".

Has bugdroid need updated to look at 'Bug:'?
Some Skia CLs have 'Bug:' but the referenced issues are not updated. Eg: https://chromium-review.googlesource.com/c/446660/

You may need to update which bug prefixes to look for in bugdroid config. However, I don't know where it is. 

It should recognize "Bug: NNN" footers since 10 months ago: https://chromium.googlesource.com/infra/infra/+/302e6e72321292f4c537d20f2cdca6c3a6e5af7c

I have evidence here that it does:
https://chromium-review.googlesource.com/c/470167/
https://bugs.chromium.org/p/chromium/issues/detail?id=601228#c8

Not sure why the skia bug didn't get updated. Probably just related to other bugdroid flakiness tracked here:
https://bugs.chromium.org/p/chromium/issues/detail?id=703548

Yes looks like you are right, I did see "Bug: NNN" work on some issues.

Separate topic: Since we made "BUG=" Gerrity we should also support "NoTry:", "TBR:", etc in the CQ. Seeing a combination of the two styles is very confusing (benjaminwagner@ ran into this today).

rmistry@ I think I've already made CQ recognize No-Try No-Presubmit. However, I didn't teach presubmit support, so TBR: might still not work :( 

And I was correct right above, machenbach@ has independently filed  issue 710803  exact for presubmit support :(
