Multi Terms: support include and exclude for terms.

[Aaron3]

When running a multi_terms aggregation, some options for terms are supported. However, include and exclude are not.

We tend to use terms with include / exclude to filter arrays of URIs on specific patterns when a single doc is related to multiple entities.

Having multi_terms has made basic pagination and sorting much easier (rather than having to sort post-query), and it would be great to be able to use it for more of our queries.
