This validates the correct abilities for both projects. Only
`read_project` isn't enough:

For the `source_project` we validate `create_merge_request_from` this
also validates that the user has developer access to the project.

For the `target_project` we validate `create_merge_reqeust_in` this
also validates that the user has access to the project's repository.

To avoid generating diffs for unrelated projects we also validate that
the projects are in the same fork network now.

This reverts commit 793be43b, reversing
changes made to 8d0b4872.

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

Notes can be unresolved, but not resolvable. Without this, the

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.

By defining the correct route helper path instead of relying on the
polymorphic route, we don't invalidate the eager-loaded relations.

In https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/20654 this job
was marked as allowing failures, but this allows developers to ignore
the results that Danger produces. Since it's not clear why the job was
allowed to fail, and since it's somewhat counter productive, we no
longer allow it to fail.
