Step 2 of #62214: Includes logic to update namespaces storage statistics

Closes #62214

See merge request gitlab-org/gitlab-ce!28996

- Add two new ActiveRecord models:
  - RootNamespaceStoragestatistics will persist root namespace statistics
  - NamespaceAggregationSchedule will save information when a new update
to the namespace statistics needs to be scheduled
- Inject into UpdateProjectStatistics concern a new callback that will
call an async job to insert a new row onto NamespaceAggregationSchedule
table
- When a new row is inserted a new job is scheduled. This job will
update call an specific service to update the statistics and after that
it will delete thee aggregated scheduled row
- The RefresherServices makes heavy use of arel to build composable
queries to update Namespace::RootStorageStatistics attributes.
- Add an extra worker to traverse pending rows on
NAmespace::AggregationSchedule table and schedule a worker for each one
of this rows.
- Add an extra worker to traverse pending rows on
NAmespace::AggregationSchedule table and schedule a worker for each one
of this rows

Now that application settings are no longer dominating network traffic,
we see that the Feature#persisted_names is using a significant amount of
CPU and network bandwidth for Redis. Move this cache into the
thread-local memory storage to reduce Redis overhead.

If an entry has been removed from the tree and later, during the same

should allow for that as long as the original entry is marked with
`deleted`.

Add a memory cache local to the thread to reduce Redis load

Closes #63977

See merge request gitlab-org/gitlab-ce!30233

The junit reports are creating 90mb files inside of redis for
`gitlab-ce/ee` project. There is an ongoing production incident
https://gitlab.com/gitlab-com/gl-infra/production/issues/928 that is
because of high CPU uitlaization on the redis nodes. GitLab-ce/ee are
the highest consumers of memory becuase of these junit reports.

This is a bandage until we can scale redis properly.
