[stork-users] Subnet prefix and shared network name in prometheus metrics

[Andrey Kostin]

One more question, with subnet_cmds enabled, does Kea still continues to 
report stats without 'prefix' and 'shared_network' labels?
After enabling it I see data in both variants:
{
   "__name__": "kea_dhcp4_pool_addresses_assigned_total",
   "instance": "X.X.X.X:9547",
   "job": "kea",
   "pool_id": "0",
   "prefix": "X.X.X.X/22",
   "shared_network": "olt01",
   "subnet": "X.X.X.X/22",
   "subnet_id": "1"
}
{
   "__name__": "kea_dhcp4_pool_addresses_assigned_total",
   "instance": "X.X.X.X:9547",
   "job": "kea",
   "pool_id": "0",
   "subnet": "1",
   "subnet_id": "1"
}

Kind regards,
Andrey
