For projects not using any CI, enabling merge only when pipeline succeeds
caused merge requests to be in unmergeable state, which caused significant
confusion.

Avoid caching BroadcastMessage as an ActiveRecord object

Closes #55034

See merge request gitlab-org/gitlab-ce!23662

There is a combination of few strategies implemented here:

1. Few relations were eager loaded
2. Changed few polymorphic routes to specific ones so we don't have to
   use `#becomes(Namespace)` which doesn't preserve association cache

Previously, the GitHub importer would only work if the site configured
an OAuth2 provider were configured. Users attempting to import via a
GitHub personal access token would see an Error 500 due to a failed
redirection. We fix this by only doing the redirection if the provider
has been configured and allowing users to see the new import page.
