Now we have cluster_id, state index, we don't the cluster_id index as
well.

This improves query performance by causing the query planner to choose
deployments_cluster_status_idx over environments_pkey, which improves
the query as environments_pkey is far bigger.

For Environment.deployed_to_cluster

- GitLab Premium feature. Adds cluster_deployments license feature

- Finder for Cluster's environments. Returns a scope for the cluster's
environments. If no permission, returns a None scope

- Add a new serializer to represent environments for a cluster. These
can be for a group cluster so we cannot restrict to a single project
(like EnvironmentEntity currently does)

- Load environments for a cluster. We need it to return where the
environment's latest deployment is to a cluster. (and not the latest
deployment to that cluster).

- Add n+1 request spec.

Properly delete files when a package is removed

See merge request gitlab-org/gitlab-ee!15634

Both CarrierWave and ProjectStatistics relies on record deletion to
cleanup storage and update statistics.

We delete Packages instead of PackageFiles and the record deletion is
performed by the DB.

This commit introduce a dependent: :destroy on Package-PackageFiles
relation.

we always reset the minutes for all namespaces.
