Optimize the repos API query #5451

The goal of this PR is to speed up the API endpoint. Specifically this is used on the repository import page and we've seen some timeouts.

  • Adds an index to Project.repo. This is queried heavily and without an index we are looking at a full table scan. This is useful not just here but elsewhere as well.
  • There is a straight forward select_related optimization on repository organizations
  • In order to disallow importing duplicate repos, we currently do a rather inefficient fuzzy match on repositories. This query is done for each repository in the query resulting in up to 15 additional queries (each of which currently results in a full table scan). This change attempts to optimize this matching query but it isn't totally lossless:
    • The change will no longer find case insensitive matches
    • The query attempts to do a very similar fuzzy match with respect to git:// URLs or URLs ending in .git but it is not exactly the same

Fixes #5441
