Ironic. Failed to delete node. Node is locked by host.

Issue

Originally it was impossible to delete the overcloud stack: delete command failed with the following error:

The output of openstack baremetal node list command stated that one node was powered on and also was in deploying state. It was impossible to change provisioning state, maintenance mode, or simple delete this node. A same output was returned for every request by ironic:
