features:
- Starting from REST API microversion 2.34 pre-live-migration checks are
performed asynchronously. ``instance-actions`` should be used for getting
information about the checks results. New approach allows to reduce rpc
timeouts amount, as previous workflow was fully blocking and checks before
live-migration make blocking rpc request to both source and destination
compute node.
