Fix transient failure in TodoService spec

See merge request !9797

# Conflicts:
#	doc/api/v3_to_v4.md

For reasons unknown, the lack of `and_call_original` on this message
expectation was causing a transient failure depending on test order. We
narrowed it down using `rspec --bisect` to the following order:

    spec/requests/openid_connect_spec.rb:123 spec/services/todo_service_spec.rb:751

API: Get list of jobs for a pipeline

Closes #26843

See merge request !9727

`Kaminari.paginate_array` takes some options, most relevant of which is
a `total_count` parameter. Using the `commit_count` for `total_count`
lets us correctly treat the return of `Repository#commits` as a subset
of all the commits we may wish to list.

Addition of a new `Repository#commit_count_for_ref` method was
necessarry to allow the user to start from an arbitrary ref.

Ref #1381

Remove unecessary endpoint from repository, add compatibility endpoints for v3 and several improvements

Allow issues in boards to be ordered

Closes #21264

See merge request !8916

This should ensure that connections obtained before starting Sidekiq are
not leaked, leading to connection timeouts.

Fixes gitlab-com/infrastructure#1139

And V4 is the preferred version to be used, because V3 will be removed
in 9.4 (or later).

It returns all projects visible for the authenticated user, not just
the project they are member of.

It was actually not used anywhere.

Since issues also accepts the query parameter iids[]=, also make it
possible query scope like that.

Add endpoint to get the jobs scoped to a pipeline.

Align bulk update issues button to the right
