Xavier Morel ea410ab6d1 [ADD] forwardport: automatic branch deleter
If a PR is *merged*, enqueue it for deletion (with a 2 weeks delay).

Mainly to avoid FW branches staying around long after they've been
merged (possibly eventually closed?), will also clean up regular
merged branches, including historical merges forgotten by their
author.

"""
Technically could be independent from mergebot but would require a lot of
duplicate work e.g. keeping track of statuses (including on commits which
might not be in PRs yet), handling co-dependent PRs, ...
However extending the mergebot also leads to messiness: fpbot should have
its own user / feedback / API keys, mergebot and fpbot both have branch
ordering but for mergebot it's completely cosmetics, being slaved to mergebot
means PR creation is trickier (as mergebot assumes opened event will always
lead to PR creation but fpbot wants to attach meaning to the PR when setting
it up), ...
