[Haskell-cafe] Final steps in GHC's Trac-to-GitLab migration

[Ömer Sinan Ağacan]

This look great, thanks to everyone involved!

Some feedback:

- When I click to the "Wiki" link on the left it opens "Home" page and I don't
  know how to go to the index from there. I think we may want index to be the
  home page for the wiki?

- Redirects don't seem to work:
  https://gitlab.staging.haskell.org/ghc/ghc/wikis/commentary/rts/heap-objects

- Comparing these two pages:

  https://ghc.haskell.org/trac/ghc/wiki/Commentary/Rts/Storage/HeapObjects?redirectedfrom=Commentary/Rts/HeapObjects
  https://gitlab.staging.haskell.org/ghc/ghc/wikis/commentary/rts/storage/heap-objects

  The Gitlab page doesn't have images that Trac page has. Secondly, the "_|_"
  string used in the Trac page is migrated as italic "|" in Gitlab.

>
>  * We are missing only two tickets (#1436 and #2074 which will require a
>    bit of manual intervention to import due to extremely large
>    description lengths)
>
>  * A variety of markup issues have been resolved
>
>  * More metadata is now preserved via labels. We may choose to
>    reorganize or eliminate some of these labels in time but it's easier
>    to remove metadata after import than it is to reintroduce it. The
>    logic which maps Trac metadata to GitLab labels can be found here [2]
>
>  * We now generate a Wiki table of contents [3] which is significantly
>    more readable than GitLab's default page list. This will be updated
>    by a cron job until underlying GitLab pages list becomes more
>    readable.
>
>  * We now generate redirects for Trac ticket and Wiki links (although
>    this isn't visible in the staging instance)
>
>  * Milestones are now properly closed when closed in Trac
>
>  * Mapping between Trac and GitLab usernames is now a bit more robust

> This will involve both gitlab.haskell.org and ghc.haskell.org being down
> for likely the entirety of the day Saturday and likely some of Sunday

>
> After the import we will wait at least a week or so before we begin the
