Steven Hawkins resolved TEIID-5346.
-----------------------------------
    Resolution: Done


Updated the logic to better propagate ndv.  Also added logic dealing with preventing the creation of unnecessary dependent joins with copy criteria - which were the majority of the test case changes.

> In the nodes above a projected literal if there are unknown cardinalities will become ndv unknown - rather than the expected ndv/nnv.
