A project is needed in order to fetch data from gitaly. Projects can be
absent from commits in certain rare situations (like when viewing a MR
of a deleted fork). In these cases, assume that the enriched data is not
needed.

See this comment:

https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/26144#note_152191106

"It's led to a dilemma about where to "fix" this in code. I'm going
to fix it by allowing CommitCollection#enrich! to just return unenriched
commits when a project is missing, essentially "silently failing". I
hope this is the right decision. It's going with the assumption that
calls in these situations in the future are not needing the full data.
The alternative would be to allow CommitCollection#enrich! to still
error, but handle it in the methods that call #enrich!, however that
might lead to brittleness in future when working with project-less MRs."

Previously the code for excluding merge commits from the commit
collection (CommitCollection#without_merge_commits) was not working
when the commits had come from a merge request. Now that this has been
fixed, these tests fails. They should always have been written to
exclude merge commits when comparing.

Allow incomplete commit records to load their full data from gitaly.

Commits can be based on a Hash of data retrieved from PostgreSQL, and
this data can be intentionally incomplete in order to save space.

A new method #gitaly? has been added to Gitlab::Git::Commit, which
returns true if the underlying data source of the Commit is a
Gitaly::GitCommit.

CommitCollection now has a method #enrich which replaces non-gitaly
commits in place with commits from gitaly.

CommitCollection#without_merge_commits has been updated to call this
method, as in order to determine a merge commit we need to have parent
data.

Send schema cache to Sentry on MissingAttributeError

See merge request gitlab-org/gitlab-ce!26331

In production, we see high error rates due to clients attempting to use
the dumb Git HTTP protocol with HEAD /foo/bar.git/info/refs
endpoint. This isn't supported and causes Error 500s because Workhorse
doesn't send along its secret because it's not proxying this request.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/54579

This avoids permission errors when importing merge requests whose
authors don't have direct access to push to the main repository.
