Issue 62684

See merge request gitlab-org/gitlab-ce!29430

The changes to the tests to support ignoring Gitea pull requests comments were
a bit of a hack. The suggestions provided by Ash McKenzie in
gitlab-org/gitlab-ce!29521 make things a bit more flexible if any future
changes need to be made to the tests.

Speed up commit loads by disabling BatchLoader replace_methods

Change SLA to target SLO for bugs and defects

We've seen a significant performance penalty when using
`BatchLoader#__replace_with!`. This defines methods on the batch loader
that proxy to the 'real' object using send. The alternative is
`method_missing`, which is slower.  However, we've noticed that
`method_missing` can be faster if:

1. The objects being loaded have a large interface.
2. We don't call too many methods on the loaded object.

In production, we've seen the rendering times of the merge request
widget increase as a result of loading commit data. BatchLoader attempts
to call replace_methods on the lazy object, but this has a significant
performance penalty. Disabling this mode
(https://github.com/exAspArk/batch-loader/pull/45) appears to cut load
times by about 50% for MergeRequestsController#show.
