feat(discoveryv2): update based on api definitions

contains some breaking model changes and new approach to handling discriminators for aggregation
types

BREAKING CHANGE: enrichmentId is now a required param for 'DocumentClassifierEnrichment' model.
'confidence' property has been removed from 'QueryResponsePassage' and 'QueryResultPassage' models.
Breaking interface changes to handling aggregation discriminators.
