Description

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.
