Ability to deploy Metron full dev as a single node (centos6) to AWS with vagrant and AMI

The pull request has two potential solutions for deploying to Metron to AWS. 

i) AWS Single Node Cluster Deployment Using Vagrant
ii) AWS Single Node Cluster Deployment Using an AMI

i) AWS Single Node Cluster Deployment Using Vagrant:
I was able to deploy Metron as a single node to AWS using Vagrant on MacOS. 

It was tested using the latest Metron code (as of 2018-01-30 - 8:00am UTC) that was in git. I'm assuming the latest that was in git is 0.4.3 that is progress.

Instructions:

ii) AWS Single Node Cluster Deployment Using an AMI:
In addition to including instructions for deploying 0.4.3 using Vagrant on a Mac I also included instructions for deploying to AWS using a preexisting AMI (I made the following AMI public as a proof-of-concept: "GCR-Xetron Demo"/"ami-93cb4ff7").  This might be the quicket option for deployment since no preinstall requirments would be needed.
