Steven Hawkins resolved TEIID-5447.
-----------------------------------
    Fix Version/s: 11.1
       Resolution: Done


Added the initial implementations and docs.  Pushdown support was not added for some sources, even though a compensating expression using other analytical functions is possible.   That can be added later if needed.

> Implementations for percent_rank, cume_dist, nth_value will have similar logic to ntile TEIID-5442 so they will be simple to add as well.
