Is your feature request related to a problem? Please describe.
The signature to query in a container is just:
query<T>(query: string | SqlQuerySpec, options?: FeedOptions): QueryIterator<T>;

Which doesn't seem to provide a way to specify request options.

Describe the solution you'd like
Would like to be able to add some of the parameters unique to RequestOptions like consistency level

Describe alternatives you've considered
Consistency level could be set via a default on the connection level, which means that in theory you could make a second connection object to use for queries that can have a lower consistency.
