Expose cycle analytics summary separately

See merge request gitlab-org/gitlab!19229

This change exposes the summary counts for group level cycle analytics
via a separate endpoint while making sure the old CA implementation is
still working.

Setting a long-term cache header works fine when not using object
storage, or when using object storage with proxy_download enabled. When
using object storage _without_ proxy_download, we send a redirect that's
cached for six months to a signed URL in object storage, but the signed
URL only works for ten minutes. So once those ten minutes are up, the
browser will keep following the (cached) redirect to a dead link.

In future, we could be more sophisticated by setting the TTL based on
the settings we're using. For now, just set this back to the pre-12.4
state of not caching content for longer than 5 minutes.

Fix file locking spec and quarantine locks directory spec

See merge request gitlab-org/gitlab!19380

Test was quarantined due to a bug: https://gitlab.com/gitlab-org/gitlab/issues/35254
Changed hardcoded "Adminstrator" in expectation to a username

In https://gitlab.com/gitlab-org/gitlab/merge_requests/16926 we added
gRPC timeouts for calls that did not previously have timeouts to prevent
Sidekiq queries from getting stuck. In addition, we also made long
timeouts 55 seconds for non-Sidekiq requests, but this meant Rake tasks
also fell into this bucket. Rake backup tasks with large repositories
would fail because the CreateBundle RPC would time out after 55 seconds.

To avoid this trap, we flip the logic of long_timeout: instead of
checking for Sidekiq (or other background jobs), we only lower the
timeout to 55 seconds if we're servicing a Web request in Puma or
Unicorn.

Add a machine-readable graphql schema

Add `edit` endpoint for Release page

See merge request gitlab-org/gitlab!17858

There are several steps to this process:

* GitLab assumes the role provided by the user and stores
  a set of temporary credentials on the provider record. By default
  these credentials are valid for one hour.

* A CloudFormation stack is created, based on the template in
  vendor/aws/cloudformation/eks_cluster.yaml. This triggers creation
  of all resources required for an EKS cluster.

* GitLab polls the status of the stack until all resources are ready,
  which takes somewhere between 10 and 15 minutes in most cases.

* When the cluster is ready, GitLab stores the cluster details and
  fetches another set of temporary credentials, this time to allow
  connecting to the cluster via Kubeclient. These credentials
  are valid for one minute.

* GitLab configures the worker nodes so that they are able to
  authenticate to the cluster, and creates a service account for
  itself for future operations.

* Finally, all details and credentials that are no longer required
  are removed.
