This moves responsibilities closer to each other.

Also fix the problem with the group being hard-coded.

Since hashes largely represent entities in the import/export,
we need to be careful not to de-dup entities that are equal up to their
respective IDs, since those might get stripped out in the future.

This introduces ProjectTreeProcessor, which de-duplicates elements in
the project tree hash for better memory efficiency during imports.

As the measurements show, the optimization only becomes useful above a
certain project size, which is why it is only enabled for projects
larger than 500MB.

Rename identifier_for_subject method to identifier_for_repositorable

See merge request gitlab-org/gitlab!23168

In https://gitlab.com/gitlab-org/gitlab/issues/39176 we're
allowing resources other than projects to have repositories
attached.

Therefore, we need to refactor those places where we use
project because it can also be a snippet. Besides, we need to
abstract this variable to something like repositorable.

In this commit we rename the method
GlRepository::RepoType#identifier_for_subject to
identifier_for_repositorable to align with this.

Fix whitesapce hack with corrected display value

Closes #121612

See merge request gitlab-org/gitlab!22553

**Note:**
- It looks like `line_content` has `display: block`
  by default. Rather than changing this everywhere
  let's just use bootstrap util class.
- We don't know why `line_content` has
  `display: block` :/

Source code won't change in CI so we don't need code-reloading

If the Bitbucket Server importer encountered any error during a pull
request import, an `undefined local variable or method 'backtrace'`
error would previously be thrown.

1ee162b6 dropped a variable that
was needed to log a clean backtrace. We add it back now so that
error recovery will work again.
