Extract vulnerabilities actions from group security vulnerabilities controller

See merge request gitlab-org/gitlab-ee!14476

Adds chaos endpoints to Sidekiq

Closes #64663

See merge request gitlab-org/gitlab-ce!30814

This allows us to more easily stub paginates_per in specs, as well as
clarifies a mystery number. (Not that it was too difficult to understand
before, but it's nicer now.)

It's unnecessarily heavy when we can modify how many occurrences we
paginate on.

(where possible)

There was some unnecessary duplication.

Since groups can contain multiple projects, we need to check that all
related vulnerabilities all included in the response.

This cleans up the code by allowing us to set subject once for each
set of action specs and redefine the params for the request under
test only when necessary.

Since there is no equivalent in CE, it doesn't need to be under the EE
namespace.

They will work with Projects or Groups now.

They were testing some functionality that is the responsibility of the
VulnerabilitiesFinder, not the controllers.

Access to these endpoints is controlled by the
Group::Security::ApplicationController, so these specs
shouldn't be shared.

Next step: smooth this puppy out
