"This is now live" automatic notifications

[AbrilRBS]

There is still some work to be done, but the gist of it is:

• ce builds set_current ... store the oldest non-notified commit, skipping if something is already stored
• ce environment refresh (and later ce instances restart) get the currently deployed version, and:
  • We ask github for the commits between both
  • Query github for the linked PRs for all those commits
  • Using GraphQL, find the linked issues for every PR, and for each:
    • Check if it already has a "This is now live" comment (Just in case)
    • Send a message saying "This is now live"
• Delete the stored commit so new build versions get logged

This would need a new ssm in aws, and I need to test it in case where no key exists (Which should be the case of env refreshes for the same version!)

The failing test comes from the branch being a bit outdated, nothing to worry about

Just ran ce notify set_base 16b176235a67f5b31f5657e2bf76e2e85d84d0f7 which is a commit from 3 days ago so we don't get spammed in case this runs unexpectedly

This could be awesome. Any chance of resurrecting this @RubenRBS ?
