/**
* Maintenance job which moves inactive nodes to dirty or parked after timeout.
*
* The timeout is in place 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.
*
* Nodes with following flags set are not reusable and will be moved to parked
* instead of dirty:
*
* - {@link Status#wantToRetire()} (when set by an operator)
* - {@link Status#wantToDeprovision()}
