A pattern that finds the partitioned table relation node inside the given plan, and returns a
pair of the partition attributes and the table relation node.
It keeps traversing down the given plan tree if there is a Project or Filter with
deterministic expressions, and returns result after reaching the partitioned table relation
node.
