The `mock_driver` is an internal task driver used mostly for testing and
simulating workloads. During the allocrunner v2 work (#4792) its name
changed from `mock_driver` to just `mock` and then back to
`mock_driver`, but the fingreprint key was kept as `driver.mock`.
This results in tasks configured with `driver = "mock"` to be scheduled
(because Nomad thinks the client has a task driver called `mock`), but
fail to actually run (because the Nomad client can't find a driver
called `mock` in its catalog).
Fingerprinting the right name prevents the job from being scheduled in
the first place.
Also removes mentions of the mock driver from documentation since its an
internal driver and not available in any production release.
Clarify the difference between the `/client` and `/node` endpoints and
link from one to the other to help users discover the endpoint they are
looking for.
Also update the `/client` page description and dynamic nod metadata
section headers to help the page be more discoverable by search engines.
Implement scheduler support for node pool:
* When a scheduler is invoked, we get a set of the ready nodes in the DCs that
are allowed for that job. Extend the filter to include the node pool.
* Ensure that changes to a job's node pool are picked up as destructive
allocation updates.
* Add `NodesInPool` as a metric to all reporting done by the scheduler.
* Add the node-in-pool the filter to the `Node.Register` RPC so that we don't
generate spurious evals for nodes in the wrong pool.
* Add os to NodeListStub struct.

(default, verbose) of the `node status` command.
