*Design doc attached*

- psutil is an open source python library and proved API to query system metrics. It incorporates native code which is platform dependent and need to built using the maven pom.
- Dependencies on "gcc" and "python-devel"

This Epic covers packaging and implementation of collecting metrics from host and processes running on a host as described in the design doc.

- The footprint of this host metric monitor process should be minimal on the host OS.
- There should be capability to locally persist data for a configurable amount of time if collector is unavailable.
- Include clear entry points for:
Process start, stop, restart and status so that ambari agent can manage / monitor the host metric monitor.
