Make yaml viz works with extensions other than .gitlab-ci.yml

Closes #249316

See merge request gitlab-org/gitlab!42632

Instead of relying on a regexp in the frontend which

have custom gitlab-ci names, this is in sync with
the API to determine that we are editing a config
file.

Add the `blob:` search filter to search by Git object-id

Closes #251223

See merge request gitlab-org/gitlab!42752

It appears that during `hot-reload` there is very
often the race condition: class gets loaded,
but we cannot properly trigger `load_all!`
before code might be interested in checking feature flag
state

There's also one missing `type: :ops` for supporting `sidekiq`
