This adds a new `pause_until` configuration option for pausing
consumers.
It can either be set when the consumer is created (but not via a
standard consumer update) or it can be changed later by using the new
`$JS.API.CONSUMER.PAUSE.*.*` API endpoint by sending:
```
{"pause_until": "2024-02-08T19:00:00Z"}
```
Any time that is in the past, or a zero timestamp, is considered as
"unpaused". Once the consumer reaches the `pause_until` time, messages
will start flowing again automatically.
The consumer info will additionally include `paused` (type `bool`) and,
if paused, a `pause_remaining` (type `time.Duration`) to report the
pause status.
Also adds `$JS.EVENT.ADVISORY.CONSUMER.PAUSE.*.*` advisory messages
which are sent when pausing and unpausing (i.e. reaching the pause
deadline).
Idle heartbeats continue to be sent while the consumer is paused to
satisfy liveness checks.
**Before merge:** nats-io/nats.go#1554 and `go.mod` updated.

This is to support work on pausing consumers.
Will remain in draft state until we're all happy with the API shape.
