Description

Node labels need to be passed into "YuniKorn Core" via "YuniKorn Scheduler Interface" (YK SI) as node attributes. It then can be considered during node sorting.

In particular, to keep the protobuf value type of node attributes still string, we plan to marshal node labels (map[string]string) into a JSON string before passing to YK SI.
