Power fault recovery: apply fault
This patch implements setting and using the fault field.
For each case currently maintenance is set to True, the fault is set
accordingly. A periodic task is added to check power state for nodes
in maintenance due to power failure, maintenance is cleared if the
power state of a node can be retrieved.
When a node is taken out of maintenance by user, the fault is
cleared (if there is any).
