TODO:

• [x] Add local persistence option.
• [x] Handle node naming when adding new nodes and nodes already exit. e.g. If host-1 and host-2 exist and the user asks to add 2 more hosts, we should name them host-3 and host-4.
• [ ] Fix Azure Image Selection, currently nothing returns from the Azure Images API. We've hard coded a version of Ubuntu for now.
• [x] Vendor Dependencies
• [ ] Automated Build/Release
• [ ] Update README to reflect migration to go
• [ ] Figure out how we should version the terraform modules. ref=tag/commit/branch/etc...
