add a flag to revert to the prior behavior (TEIID-4557)

Several customers are seeing errors[1] after https://issues.jboss.org/browse/TEIID-4557 was implemented and generally have to drop the max-active-plans to 1 for their queries to succeed. Can a flag be added to revert to the behavior prior to TEIID-4557?
