Review Comment:
We can also just get userId and sessionId from server via request, instead
of passing from here.
But that would require we update
[transformRelation()](https://github.com/apache/spark/blob/master/connector/connect/server/src/main/scala/org/apache/spark/sql/connect/planner/SparkConnectPlanner.scala#L87)
to take into two more parameters, which means all all those `transform...()`
need to be updated to have two more parameter.
