When deleting a pipeline, only some of the cache structures were being
expired, but not the full pipeline list. We have to synchronously
schedule a pipeline cache expiration because the pipeline will be
deleted if the Sidekiq expiration job picks it up. To do this, properly
extract all the logic buried in the Sidekiq worker into a service, and
then call the service.

When a pipeline is for a forked merge request, we have to invalidate
the ETag for both the target and source project pipelines. Before
we were only invalidating the target project's pipeline.
Uses `list_commits_by_oid` on the CommitService, to request the needed
commits for pipelines. These commits are needed to display the user that
created the commit and the commit title.
This includes fixes for tests failing that depended on the commit
being `nil`. However, now these are batch loaded, this doesn't happen
anymore and the commits are an instance of BatchLoader.
