Subject: [PATCH] client/authority-discovery: Add metric exposing priority
group size (#5707)
Expose the amount of addresses that are passed from the authority
discovery module down to the network peer set manager as a priority
group in order to connect to the corresponding nodes.
```
authority_discovery_priority_group_size 10
```
