> Background: SystemBolt is reserved component for each worker which exposes worker level
metrics like Memory, GC, and uptime, and so on.
> All SystemBolts have -1 as task id, so identifying SystemBolt components to task id as
same as normal components will fail.
> Since each worker is identified by (worker host, port) pair, we can add hostname and
port to metric name to make metric name unique.
> Since it's only for SystemBolt, instead of adding hostname and port to all of metrics,
we can add these to specific metrics which are coming from SystemBolt.
