Packer Integration for Base Machine Setup

@StevenChin  All conversation and commits will go here until this feature is complete

TODOs: 
- Move most scripts to be managed by ansible
- Process Cleanup
- Create AMI image
- Update Readme
- Rebase all commits into one commit when feature done

What's Done:
- Vagrant box image created with `packer`
- Ansible roles shared between `packer` and `vagrant`
- install plugin files from a url instead of putting file in the repository
- Add SauveLabs.py to `/usr/local/bin`
move this to ansible
