docs: Context manager that sets a vagrant VM
          as the remote host.
  
          Use this context manager inside a task to run commands
          on your current Vagrant box::
  
              from burlap.vagrant import vagrant_settings
  
              with vagrant_settings():
                  run('hostname')
