Allow scheduling jobs in batch with contexts

See merge request gitlab-org/gitlab!23519

This adds helper methods for the `bulk_perform_in` and
`bulk_perform_async` methods that allow specifying a context per job.

Scheduling jobs with contexts that need to be different based on the
arguments passed can be done by passing in an array of objects, and
defining how to build arguments and contexts for those objects.

For example:
      ProjectImportScheduleWorker.bulk_perform_async_with_contexts(
        projects,
        arguments_proc: -> (project) { project.id },
        context_proc: -> (project) { { project: project } }
      )

This will schedule `ProjectImportScheduleWorker` jobs called with the
project.id. And will create contexts using the project. The developers
need to make sure that the required resources for building a context
are loaded: The route and the namespace of a project.

The batch context will be stored on the worker class when scheduling
the job, so the sidekiq middleware can fetch the right context based
on those arguments and apply them to the job when scheduling it.

This also implements this method for the `UpdateAllMirrorsWorker`
which schedules `ProjectImportScheduleWorker` in batch. When adding
this, the `ProjectImportScheduleWorker`-jobs will have a context.

however due to the paragraph being outdented, it appears in the docs
without a paragraph.
