Wez Furlong eb6232f582 Add basic suspension of scheduled and ready queues ...

These are two different groups of queues, so there are two different
sets of things to manage them.

kcli now has `suspend(-list|cancel)?` and
`suspend-ready-q(-list|cancel)?` subcommands for establishing a
suspension, listing the suspensions and cancelling a suspension
in the scheduled-q and ready-q namespaces respectively.

The names of the ready queues can be derived from the metrics API:

```console
$ curl -s 'http://localhost:8000/metrics.json'  | jq .
...
  "ready_count": {
    "help": "number of messages in the ready queue",
    "type": "gauge",
    "value": {
      "service": {
        "smtp_client:source2->(in1-smtp|in2-smtp).messagingengine.com": 0.0
      }
    }
  },
...
```

From the above, `source2->(in1-smtp|in2-smtp).messagingengine.com` is
the name of the underlying ready queue.

We can and probably should add something to `kcli` to make that slightly
easier to review and manage for the operator.
