Along with some common checks, the Publishing API has the following
specific checks.

## `sidekiq_queue_latency`

The latency on the `downstream_high` Sidekiq queue is checked, as this
is critical for prompt publishing.

If there is a backlog in the queue, one possible workaround is to try
restarting Sidekiq. This has been used to workaround issues where the
Sidekiq jobs have got stuck when encountering issues with RabbitMQ.

This should be visible when someone clicks on the relevant link in
Icinga.

This is following up on the addition of a check for the
`downstream_high` Sidekiq queue, which has got stuck a few times
recently.
