[deployment handler] Refactor the old installer_handler

This is a util library to interact with the
deployment regardless of the installer.

Objects:
  - Deployment
  - Node
  - DeploymentHandler
     - ApexAdapter
     - FuelAdapter
  - Factory

The installer adapters implement some of the
abstract functions of DeploymentHandler class
that can't be generalized.
