Docucumenation for installing Hawkular (Manually)

[mtho11]

This is a documentation task for the steps to install Hawkular manually instead of via docker. While using docker is the quickest/easiest way to get Hawkular running with Manageiq (with HawkInit being another quick and easy way). There are a couple use cases when this manual setup is very useful:

1. Debugging via agent logs. Sometimes it is necessary to turn on agent level debug logs to diagnose what is being sent and processed by the agent.
2. Working with portions of Hawkular that have not yet been released yet. For instance, an agent operation that only lives in a branch. Or an unreleased version of Hawkular Alerts.

The section to update is here: https://github.com/ManageIQ/manageiq-providers-hawkular/blob/master/GETTING_STARTED.md#manually
