    METRON-1445: Update performance tuning guide with more explicit parameter 

    ## Contributor Comments
    The current performance tuning guide can be challenging to follow for those 
not familiar with the system. This PR updates the guide to provide details 
about how and where to find tuning parameters along with details as to how the 
properties are materialized in a running topology.
    Additionally, a supplement to the tuning guide has been provided to pull 
Metron cluster debugging info into a tarball. As pertains to the perf guide, it 
captures the state of Ambari configuration, flux files, properties files, and 
zk config. This helps users confirm system state as they make tuning changes.
