nodeIdPrefix property
Prefix of node_ids in case of multislice request.
Should follow the ^[A-Za-z0-9_.~+%-]+$
regex format. If node_count = 3
and node_id_prefix = "np", node ids of nodes created will be "np-0",
"np-1", "np-2". If this field is not provided we use queued_resource_id as
the node_id_prefix.
Optional.
Implementation
core.String? nodeIdPrefix;
