Terraform support

[jackivanov]

We definitely need to consider moving to terraform
I suggest to replace all the cloud roles to terraform states and keep the local role only to run ansible after terraform done with clouds.

pros:

1. No python libraries anymore. No mess. Only a file to run all the provides. Very simple installation and configuration.
2. A lot of provides supported. We can be very flexible and more modular. Related to Potential new VPS providers for the installer #623
3. Multi environment support
4. A way to destroy the infrastructure without touching web
5. ... ?

cons:

1. ... ?

I could write a Packer script to build an Amazon AWS AMI, then a terraform script to deploy the security groups, etc. and the AMI. Sound like a good starting point? I don't know much about Google, Azure, or Digital Ocean.
