Migrate from Trac to GitLab

[May-Lee]

Actions to resolve this issue:

Set a deadline for finding a contractor.

Set this deadline knowing that we would have to schedule about a month to do this on our own, if no contractor has been found.

Choose the month this work would take place.

Some project notes:
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Migration in Four Phases (budget is 1k - 2k phase)

1. Migrate Tickets, Ticket History (including attachemnts, patches, comments - okay if it has to be just one long thing) from Trac to GitLab
2. Migrate CI Config from GitHub to GitLab
3. Migrate GitHub PRs to GitLab - GitLab has a button to import GH PRs; making a GitLab export version
   NOTE: Migration must be ended before we add an issue tracker
4. Add issue tracker on GitLab
   OTHER:We likely won't move the Wiki, but if so, it would be contents and edit history
   Don't worry about milestones
   Person should overwhelmingly use IRC
   Work should be done in a public repo and published

Ultimate goal is a self-hosted GitLab instance, but that would require some kindof support (managed offering is 800/mo including licenses and server support)
Need to get issue tracker
Consensus reached in March was Sajith was going to look more into it, with zFECas a test case
Jean-Paul has suggested using the GitLab export format from the Trac DB(presumably an artifact) vs. the GitLab API
We need to come up with a budget for that
At this stage, this type of thing should be offered to the Discourse, mailing list, and linked to the IRC
Should parts of the Trac be archived? As they might actually no longer be
relevant (e.g., general speculative features older than 5 years)
GitLab to GitLab is about 30 hours
Dealing with:In-progress PRs Links between tickets should still work
Links between pages should still work
Authorship is important
Custom metadata to tickets

Of course someone has to run it but it doesn't seem clear that we have to out-source the management.

We have servers with Hetzner and they now have some apps, including GitLab:
