This adds a gauge exposing the configured number of threads we expect
to be running and using the database called
`gitlab_ruby_threads_concurrency_total`.

It also adds `gitlab_ruby_threads_total`.

This gauge has a `thread_name` label used to identify the kind of
thread. For unnamed threads the label will contain `unnamed`.

To identify sidekiq worker threads, that before had no name, we set it
in the `Gitlab::SidekiqMiddleware::Metrics` server middleware. So we
can distinguish it from other running threads.

The `uses_db_connection` label indicates if the thread has at some
point connected to the database. We use the same subscriber as we do
for the query counts to flip this value on the thread.

Fix order-dependent Geo spec failure

Closes #230333

See merge request gitlab-org/gitlab!37280

Currently `before_all` doesn't rollback data properly between examples
when the data is in the Geo tracking database. We use `before` instead
of `before_all` to avoid polluting data data across examples.

Closes https://gitlab.com/gitlab-org/gitlab/-/issues/230333

Add query optimization examples in Telemetry guide

This commit adds a predefined policies to the network policies
list. This allows users to quickly try out network policies against
deployment platform.

This enables re-use of authorization code. Also make use to Rails' Token
authorization code

- Return agent_id in response if present
- Receive token via Authorization header

Use standard way for Authorization which is the header. We currently not
care about the
Authorization type but may enforce this in future

Adds /project_info endpoint. Only for public projects. We will sort out
authorization for internal and private projects later

Remove need to hack around InternalHelpers. InternalHelpers assumes an
actor (we don't have it) and params (don't have that either). So get the
required data directly instead.

- cluster_agent
- cluster_agent_tokens

Adds encrypted token using TokenAuthenticatable module

Add has_many :cluster_agents

Add to spec all_models.yml checklist. cluster_agents should not be
exported as part of project export, so not putting in import_export.yml.
