2. schema: Support more checkout data in v4.5 …

   Add support for three more checkout fields: `git_commit_tags`,
   `git_commit_message`, and `git_repository_branch_tip`.
   
   The `git_commit_tags` is an array of strings representing annotated tags
   pointing directly at the commit being checked out, as seen in the
   source repository. I.e. the output of `git tag --points-at <commit>`.
   Set to an empty array, if the commit has no tags.
   
   The `git_commit_message` is intended to hold the complete message of the
   commit being checked out, *both* subject and body. I.e. the output of
   `git show -s --format=%B`. We're putting the subject and the body
   together, as it's quite easy to extract the subject in SQL, while
   full-text search is easier and more efficient to do over a single
   column.
   
   Finally, the `git_repository_branch_tip` is a boolean flag, which should
   be set to `true`, when the commit being checked out is at the tip of the
   branch at the moment of the checkout (as specified in `start_time`).
   Essentially, if you're always testing only the tip of the branch, you
   can set this to `true` unconditionally. This flag would let us extract
   the checkouts which represented the branch state over time, and produce
   a rough history of branch changes, which we can then use for
   (regression) analysis and graphs, in lieu of actual commit graph
   walking.
