Migrate Travis CI to GitHub Apps

[foolip]

Like whatwg/meta#96, and possible we can learn from that issue, or vice versa.

This is blocked on us transitioning from travis-ci.org to travis-ci.com, which is blocked on Travis making that possible while preserving build history. I forwarded some Travis support replies in https://groups.google.com/a/chromium.org/d/msg/ecosystem-infra/fb2H4CMlqN0/I8gjvD2wCQAJ. Leaving as priority:roadmap as it was "coming months".

@foolip any movement from Travis?

[foolip]

My last contact with Travis about this was Sep 6, when the reply was "We'll keep you posted when the migration is possible." I'll ask again now.

Reply is:

We don't have a hard timeline in place right now- although there is a roadmap we're actively working on and making good progress, we don't want to give a hard date just now. However, I will say that, from the way things look right now, we should see the migration happening soonish- within the next few months.

Sorry I'm not able to give a more concrete answer here! I hope it at least helps to know that we are making progress on this internally and hope to have it rolled out fully soon- there's just some housekeeping and opportunities for improvement we need to do before we can transition fully to travis-ci.com.

Wait it is :)

Friendly ecosystem infra rotation ping

This issue has gotten stale. Any updates @foolip?

[foolip]

We are now able to do this, and we've already migrated the wpt.fyi repo. @web-platform-tests/admins does anyone have concerns about completing the transition for all other repos? The process is described in https://docs.travis-ci.com/user/open-source-repository-migration/ and the only thing to keep in mind is cron jobs. If there are cron jobs, they have to be deleted and recreated, and there has to be a commit to the branch they're attached to after they're created. This will only impact results-analysis, however.

No concerns from me 🙂

Done in #14499, I forgot I had opened this issue.

[zcorpan]

OK. So this can be closed? Reopen if I misunderstood.

[foolip]

Yes, I just pressed the wrong button :)
