shards: prometheus metrics for sharded search
We add several metrics and add the prometheus http handler to zoekt-webserver
if pprof is enabled.
- Gauges for number of running searches and lists.
- Gauges for number of searches and lists within a shard.
- Histogram for search duration.
- Counter for number of search failures.
- A counter per zoekt.Stats
The gauge should for searches should help with noticing a queue forming. The
gauges in shards should be bounded, but are useful to understand load. The
rest of the metrics are pretty straightforward.
