  When we launch for the first time, we need to :
  A - Check if VirtualBox and Putty, Ssh are installed
  B - Always get the list of VM
  C - json file exist?
    D - If not, ask for installation:
        List of Virtualbox's VMs:
            1. "CentOS 7"
            2. "Ubuntu 16.04.3 Server"

        Select the vm to launch: _
    D - Save new JSON file
  E - If yes, check if the default vm is still in the list we got from (B)
