Task #5795
Automatically cherry pick bug fixes to the latest release branch
100%
Description
Have Travis check for issues tagged with "Needs Cherry Pick" and create a PR with these issues against the latest release branch.
Design¶
When Travis runs its cron job, have it check for any merged PR labeled with "Needs Cherry Pick". It should create a PR with these changes if the cherry picks all succeed. Travis should also remove the label from PRs.
If any of cherry picks fail, the job should fail. PRs in this case don't get updated and the release lead should create the PR manually and remove the "Needs Cherry Pick" label.
The job should be controlled by a plugin_template variable (perhaps perform_cherry_pick?). I imagine we'll also need to have a variable to store the latest release branch name.
The Github user credentials, which are needed to open a PR and update PR labels, should be stored/encrypted in Travis settings. I think we might be able to leverage the @pulpbot account on Github.

The cherry pick process failed:
https://travis-ci.com/pulp/pulpcore/jobs/269037561
The issue is that there are three ways to "merge" PRs in github. The first is by merging and the other two are rebasing and squashing. In the merge case, the SHAs in the PR match the commits in the repository. The cherry pick code uses these SHAs to cherry pick the changes from the PR.
In the other cases however, the SHAs are different because the changes have been rebased or squashed. The cherry pick code doesn't handle this possibility and will need to.

Here is the fix to handle squashes and rebases. Warning, it's ugly.
