Associates metadata with entities in the entity hierarchy. This metadata can be of various types (eg. Credentials). Returns a list of entity id and corresponding errors encountered (if any) while associating metadata with that entity. Note that a partial success response is possible where we succeed in associating metadata with some of the entities but fail for others. The API also expects the entities being updated belong to same source.
