Enables authorizations to be defined on GraphQL Types.

    module Types
      class ProjectType < BaseObject
        authorize :read_project
      end
    end

If a field has authorizations defined on it, and the return type of the
field also has authorizations defined on it. then all of the combined
permissions in the authorizations will be checked and must pass.

Connection fields are checked by "digging" to find the type class of the
"node" field in the expected location of edges->node.

Stop calling UnlinkRepositoryFromObjectPool RPC

Closes #59777

See merge request gitlab-org/gitlab-ce!26821

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/59777.

In earlier iterations of our implementation of Git object deduplication
we thought we would be making extensive use of Git remotes in pool
repositories in the future, and that we should manage these remotes
carefully from the start. We now expect we only care about one remote,
namely the source project. The other remotes are there only for forensic
purposes.

Before this MR we tried to also remove pool remotes when member projects
got deleted, with the UnlinkRepositoryFromObjectPool RPC. This is
fragile when there are race conditions (see
https://gitlab.com/gitlab-org/gitaly/issues/1568#note_153955926). We
have spent some time making this RPC less fragile in
https://gitlab.com/gitlab-org/gitaly/merge_requests/1151 but looking at
this problem again, I think we should just stop calling it.

Fixed positioning of the diff tree list on mobile

Closes #59739

See merge request gitlab-org/gitlab-ce!26820

For each pipeline, the controller will call `Pipeline#latest?` to
determine if the pipeline's ref is the latest for that branch.
Since it's likely that the same branches are being used in each
pipeline, we can reduce Gitaly overhead by caching the results
of the FindCommit call.

Monitor GraphQL with Prometheus

In graphql 1.8.11 is added prometheus class but it's not very useful
for us because it uses prometheus_exporter to export results.
