Add support for "for each row" update procedures and new default handling

Teiid now has support for "for each row" procedures that can be used instead of update procedures. The initial plan is to support both our old update procedures and the new for each row handling.

Default update handling has has been updated to no longer require a procedure - Teiid in fact expects a null value to indicate a default procedure.

In dev emails it was brought up that the specific insert/update/delete enabled toggle may not be needed anymore given the improvement in the default handling. One possibility is to change its meaning to something like "must be updatable". In which case the validation problems will need to be separated out by procedure type and then elevated to errors.
