Support power state change callbacks to nova using ksa_adapter
Add power state change callbacks of an instance to nova by
performing API requests. Whenever there is a change in the
power state of a physical instance (example a "power on"
or "power off" IPMI command is issued or the periodic
``_sync_power_states`` task detects a change in power state)
ironic will create and send a ``power-update`` external event
to nova using which nova will update the power state of the
instance in its database. By conveying the power state changes
to nova, ironic becomes the source of truth thus preventing
nova from forcing wrong power states on the instance during
the nova-ironic periodic sync. It also adds the possibility of
bringing up/down a physical instance through the ironic API
even if it was put down/up through the nova API.
Note that ironic only sends requests to nova if the target
power state is either "power on" or "power off". Other error
states will be ignored. In cases where the power state change
is originally coming from nova, the event will still be
created and sent to nova and on the nova side it will be a
no-op with a debug log saying the node is already powering on/off.
NOTE: Although an exclusive lock (task_manager.upgrade_lock()
method) is used when calling the nova API to send events,
there can still be a race condition if the nova-ironic power sync
happens to happen a nano-second before the power state change
event is received from ironic in which case the nova state will
be forced on the node.
