Adds a new /svc group under each pool which contains the following set of metrics: * leader (gauge): Current pool service leader rank * map_version (counter): Current pool map version * open_pool_handles (gauge): Current count of open handles * total_ranks (gauge): Number of ranks in pool map * degraded_ranks (gauge): Number of ranks with disabled targets * total_targets (gauge): Number of targets in pool map * disabled_targets (gauge): Number of targets marked disabled * draining_targets (gauge): Number of targets in draining state For non-leader ranks, the service metrics will have zero values. Telemetry consumers may positively identify the current leader by checking the value of map_version, which will always be non-zero for the leader.
