Issue:
Parse Indexer Unavailable Errors to emit `unavailable_indexers` metric
# Details

**Describe the solution you'd like:**

Prowlarr, interestingly, does not consider indexers which have been marked "unavailable" as "disabled", so they don't increment the disabled metric (It only counts indexers which were manually disabled). Unavailable indexers seems like a metric that will commonly want to be alerted on, but the only place it shows up is as a health issue (of source `IndexerLongTermStatusCheck`). We should consider special casing this error type to emit an unavailable indexer metric. The actual logic isn't particularly difficulty, but system health issues are collected by a common collector, so we probably need to think a little bit about where and how to collect this and emit it as another metric.

**Description of the change**

<!-- Describe the scope of your change - i.e. what the change does. -->

Prowlarr doesn't consider indexers that it's marked unavailable due to errors as "disabled", it only considers them "unavailable". This unavailable status doesn't have a metric of it's own, it just shows up as a health message, with the server names in a comma delimited list in the message.

This change looks for `IndexerStatusCheck` health messages, and emits an extra metric per indexer. 

**Benefits**

<!-- What benefits will be realized by the code change? -->

This extra metric will make it much simpler to build alarms, as one can key off the number of indexers unavailable (or even % of indexers unavailable by dividing this by `indexers_total` or `indexers_enabled`)
