  # Some CPIs might power off and then power on vm to reconfigure network adapters,
  # so Director needs to wait for agent to become responsive

  # Once CPI has configured the vm and stored the new network settings at the registry,
  # we restart the agent via a 'prepare_network_change' message in order for the agent
  # to pick up the new network settings.

  # Since current implementation of prepare_network_change is to kill the agent
  # we need to wait until the agent is ready. However, we want to avoid
  # talking to the old agent, so we need to wait for it to die.
