Bug Description

Commissioning is not working in the Garage MAAS with MAAS 1.6b4.

Credentials have been validated. Asking MAAS to commission the node does not turn on the node at all. No OOPS is generated. The node then stays in a "Commissioning" state indefinitely.

Hmm... this time it seems the problem was that a celery daemon was silently not running.

Having parts of MAAS silently not running is very poor user experience - when it's broken it's useless but very difficult to know why that is.

Celery is being deprecated this cycle (for removal in a future release but we need to keep a window of RC/CC compatibility for now). When the internal bi-directional RPC is up and away, spotting dead clusters will be very easy.

The fix for this is twofold:
- whether or not the clusters are connected is displayed on the cluster listing page.
- one gets instant feedback (a message in the UI, a 503 response in the API) when one tries to perform an action (like starting a node) when a cluster isn't connected.

It is not visible if I have to go into the cluster listing to see if
there is a problem! So, if any clusters / maas components are not
responding, then we should have an alert on the global header bar which
links to the more detailed listing of clusters and their statuses.
