/**
* Returns the list of binding keys possessing the keyedReferenceGroups in the passed category bag.
* Output is restricted by list of binding keys passed in. If null, all binding templates are searched.
* Output is produced by building the appropriate JPA query based on input and find qualifiers.
*
* From specification:
* "This optional argument is a list of category references in the form of keyedReference elements and keyedReferenceGroup
* structures. When used, the returned bindingDetail for this API will contain elements matching all of the categories
* passed (logical AND by default). Specifying the appropriate findQualifiers can override this behavior.
*
* A given keyedReferenceGroup "X" (e.g., within a given categoryBag) matches a keyedReferenceGroup "Y" in the registry if
* and only if the tModelKey assigned to the keyedReferenceGroup X matches the tModelKey assigned to the keyedReferenceGroup
* Y and the set of keyedReferences in "X" are a subset of the set of keyedReferences in "Y." The order of individual
* keyedReferences within a keyedReferenceGroup is not important. Matching rules for the individual contained keyedReference
* elements are the same as above."
