Steven Hawkins resolved TEIID-1518.
-----------------------------------
Fix Version/s: 7.6
Resolution: Done
Added a result cache to subqueryawareevaluator. the cache is currently not tunable and is
conservative, but will definitely help prevent excessive subplan execution in situations
where there are a small number of correlations or at least some locality to how they are
processed.
Also moved the update of the determinism level from the functionmethod to the evaluator
since the logic in the functionmethod misses any non-deterministic function that does not
have a commandcontext parameter.
Add a correlated subquery evaluation cache
