[libvirt] [PATCH 05/10] test: Allow specifying object transient state in driver XML

[Cole Robinson]

Similar to the runstate commit, allow a block like:

  <testdriver>
    <transient/>
  </testdriver>

Wire it up for domains and networks. Generalize the boolean lookup
pattern since we are going to use it for other bits as well.
