 Description   

(probably related to SERVER-21913) but if multiple conditions are allowed, then looking up based on multiple conditions should allow more than just equality.

This could be done implicitly via SERVER-21612 in which case user would add $match after $lookup.

Resolved with work under SERVER-29072.
