This enables live migration for TPM instances with the ``host`` secret
security mode. The ``host`` security mode uses key manager service
secrets owned by the instance owner. The secret is persisted in
Libvirt and is sent over RPC to the destination during a live
migration.
The service version will be bumped in a separate patch.
