It also renames the API::PROJECT_ENDPOINT_REQUIREMENTS constant to
API::NAMESPACE_OR_PROJECT_REQUIREMENTS

As we now support getting the merge base for multiple revisions in
gitaly, we can provide this functionality in our API

Partially addresses #47424.

Had to make changes to spec files because
stubbing methods on frozen objects is a mess
in RSpec and leads to failures:

https://github.com/rspec/rspec-mocks/issues/1190

This adds an endpoint to get the common ancestor of 2 refs from the API.

Repository compare API now allows choosing straight (from..to) or merge-base diff (from...to)

[API] Fix URLs in the 'Link' header for 'GET /projects/:id/repository/contributors' when no value is passed for 'order_by' or 'sort'

Repository archives are always named `<project>-<ref>-<sha>` even if
the ref is a commit. A consequence of always including the sha even
for tags is that packaging a release is more difficult because both
the ref and sha must be known by the packager.

- add append_sha option (defaults true) to provide a method for
toggling this feature.

Support added to GitLab Workhorse by gitlab-org/gitlab-workhorse!232

Allows ordering in GET api/v4/projects/:project_id/repository/contributors
through `order_by` and `sort` params.
The available `order_by` options are: name|email|commits.
The available `sort` options are: asc|desc.
