* Prometheus: disable dynamic label lookup on big datasources

the editor sluggish

* Raise dynamic lookup threshold to 10000 metrics

* Run start tasks again

- since the API update, the URL fallback was working, but the response
format also needed adapting: `data` (v1) vs `values` (pre-v1)
- this change looks for either data or values in the response for test
and metadata requests
