/**
* Maintenance job which moves inactive nodes to dirty or parked after timeout.
*
* The timeout is in place for two reasons:
* <ul>
* <li>To ensure that the new application configuration has time to
* propagate before the node is used for something else
* <li>To provide a grace period in which nodes can be brought back to active
* if they were deactivated in error. As inactive nodes retain their state
* they can be brought back to active and correct state faster than a new node.
* </ul>
*
* Nodes with the retired flag should not be reused and will be moved to parked instead of dirty.
