1887949 - Migrate ci-configuration repo to `mozilla-releng/fxci-config` on Github

Status: ASSIGNED

(Release Engineering :: Firefox-CI Administration, task)

Description

[Andrew Halberstadt [:ahal]]

We'd like to migrate ci-configuration to Github for a number of reasons:

1. Mozilla is moving away from hg.m.o
2. Code review bot doesn't comment on phab revisions
3. Problems with hg load
4. More visible / easier to contribute to
5. PR flow is nicer (imo)

I've already set up the repo, including history:
https://github.com/mozilla-releng/fxci-config

This bug will track the switch. Roughly my plan is to:

1. Get Taskcluster CI working on the new repo
2. Announce the move a week in advance to relevant teams
3. Make the new repo the source of truth by updating cloudops-infra
4. Request the old repo be archived

I don't have an exact timeline, but ideally this will all happen in the next month or so.

This way I can keep the main branch tracking the old repo and also not break
any checks.

It looks like the trigger for that deploy pipeline is configured in Jenkins somewhere outside of that repo, so I also filed https://mozilla-hub.atlassian.net/browse/SVCSE-1852 to track the request to SRE to make that change.
