        If we want to backed resources externally we can use s3 setting this param(i.e s3://existing-bucket). 

        If default will be store on storage workspace at path set by param ws-output-path.

    - name: airgap
      description: |
          Set the machine on an airgap scenario. 

          If airgap is set an extra VM is created acting as bastion, information to access bastion is also
          added to the output folder.

          To access the target machine we need to go through the bastion
      default: 'false'

        Warning setting this param to true expose credentials 
        
        The parameter is intended to add verbosity on the task execution and also print credentials on stdout
        to easily access to remote machice
