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.

Previously, an authentication issue could manifest as an opaque and
confusing error message like
```
Error: error decoding response body: expected value at line 1 column 1
```
now we show it like:
```
Error: request status 401: Unauthorized. Response body: Missing Authorization header
```
Entries now have a uuid that identifies them within a given instance
(NOT within a cluster). The id is returned when the entry is
established:
```console
$ kcli --endpoint http://127.0.0.1:8000 bounce --everything --reason boop
{
"id": "9a946198-9351-4e0e-b460-fc84e066878a",
"bounced": {},
"total_bounced": 0
}
```
You can list entries with their remaining duration:
```console
$ kcli --endpoint http://127.0.0.1:8000 bounce-list
[
{
"id": "9a946198-9351-4e0e-b460-fc84e066878a",
"campaign": null,
"tenant": null,
"domain": null,
"reason": "boop",
"duration": "4m 57s 313ms 891us 882ns"
}
]
```
and cancel them:
```console
$ kcli --endpoint http://127.0.0.1:8000 bounce-cancel --id 9a946198-9351-4e0e-b460-fc84e066878a
removed 9a946198-9351-4e0e-b460-fc84e066878a
```
and the error case if you try it again:
```console
$ kcli --endpoint http://127.0.0.1:8000 bounce-cancel --id 9a946198-9351-4e0e-b460-fc84e066878a
Error: bounce entry 9a946198-9351-4e0e-b460-fc84e066878a not found
```
```console
$ kcli --help

Administratively bounce messages in matching queues.
Each individual message that is bounced will generate a log record capturing the event and then be removed from the spool.
Make sure that you mean it, as there is no going back!
The bounce will be applied immediately to queued messages, and the directive will remain in effect for the duration specified, causing newly received messages or messages that were in a transient state at the time the directive was received, to also be bounced as they are placed back into the matching queue(s).
Usage: kcli --endpoint <ENDPOINT> bounce [OPTIONS] --reason <REASON>
Options:
--domain <DOMAIN>
The domain name to match. If omitted, any domains will match!
--campaign <CAMPAIGN>
The campaign name to match. If omitted, any campaigns will match!
--tenant <TENANT>
The tenant name to match. If omitted, any tenant will match!
--reason <REASON>
The reason to log in the delivery logs
--everything
Purge all queues
--duration <DURATION>
