Installer adapters

This tool might be used by any project in OPNFV
to retrieve information about the deployed
OpenStack nodes.
It is python based and using paramiko.

It can:
  - get info about deployment
  - get the info about the nodes (ip, mac, ...)
  - stablish ssh connection even with ProxyCommand option
  - run remote commands
  - scp to/from nodes (i.e. fetch credentials from controller)

Added FuelAdapter as an example.
