This functionality is needed for SSH push mirroring support, which is a
CE feature.

Whenever a git push takes more than 50 seconds the user
will receive a trace from each check performed along with
their timings

GET :namespace/merge_requests/:id/ci_environments_status complexity
already reached a limit for a direct serialization from an hash
computed at within the controller function.

Here we introduce a virtual model EnvironmentStatus and its serializer.

Remove the inheritance from ::BaseService which is causing us to inherit
the initializer that has project as the first arg, as we will not have
access to project with forthcoming group clusters.

Also call install service from create service - 1 less thing to re-use

Extract TestRequest code into a spec helper. Given that we need
different behaviour for Rails 5.0 (and again in Rails 5.1!), it's handy
to have that branching behaviour in one place

This should help with code re-use when we create applications for group
level cluster next.

Change `find_or_initialize_by` to explicitly find or build the right
association based on the application name. The benefit here is that we
use the associations on @cluster rather than querying from the other
side of the association.

This enables us to have other options in the future such as passing in
`group:`.

Also, remove project arg from UpdateService, as un-used.

This will help group cluster controller to re-use this services.

This icommit adds several changes related to the same topic
- resetting a Runner registration token:

1. On Project settings page it adds a button for resetting the
   registration token and it removes the Runner token field
   that was confusing all GitLab users.

2. On Group settings page it adds the same button for resetting
   the registration token.

3. On Admin Runners settings page it moves the button to the same
   place as in Project and Group settings and it changes slightly
   the page layout to make it more similar to Group and Project
   setting pages.

4. It refactorizes a little the partial that prints runner
   registration description. Thanks to this Project, Group
   and Admin settings of the Runner are re-using the same
   code to generate the button.

5. Updates the translations of changed text.

**Notes:**
- Also exposes commit.signature_html in diffs.json

Enables frozen string for some vestigial files as
well as the following:

* app/controllers/projects/**/*.rb
* app/controllers/sherlock/**/*.rb
* app/controllers/snippets/**/*.rb
* app/controllers/users/**/*.rb

Partially addresses #47424.

This is similar to the option in the Add Existing cluster form

which most are triggered by the CodeReuse/ActiveRecord cop.

When a container registry has many tags, it's easy for the DELETE call to take more
than 60 seconds and fail. This can also leave the registry in a bad state with
null bytes since some of the images have been deleted with tags still pointing to them.
In addition, we have to prevent users from accidentally initiating the delete multiple
times or this could leave the registry with orphaned tags.

This commit also adds a flash message to notify the user the registry is scheduled
for deletion.

Closes #49926, #51063
