promquery: add BulkQueryCache

This implementation originates in Limes (imported from there at
`internal/util/promcache.go`), but I want to reuse it in Castellum where
the idea of bulk requesting and caching Prometheus metrics originates.

This implementation differs slightly from the one in Limes:

- The `Prometheus` prefix was removed from the type names.
- The `refreshRate` field was renamed to `refreshInterval`.
- The constructor method takes a Client instance instead of its Config.
- A full-featured documentation example was added to better demonstrate
  how all the pieces fit together.
