Description

AMBARI-18733 added a lot of TODO comments in order to allow agents to use their own config file.
Specifically, Hardware.py, Register.py, Facter.py, Heartbeat.py, main.py

We make sure that all aspects of the Agent are allowed to use a custom home dir and find the correct config file.
E.g., ambari-agent start --home /home/perf-0001

Add-ons:

1. Add a meaningful Role Command Order to PERF stack
