As a note, the way I tested this was running it up in a CentOS 7 VM, along
with a couple changes to get things working:
* Turning off firewalld during spinup.
* Downgrading python.x86_64 and python-libs.x86_64 to 2.7.5-48.el7 to avoid
an SSL error. Apparently 58 or whatever latest epel has causes entirely
unrelated issues with node registration in Ambari.
* Installing Metron + dependencies via Ambari.
I also ran in standard full dev to ensure that it still worked in 6.
