Revision edb85453

When unassociating from large repos, to connect repo unit with content unit pulp queries all units in the repository and then query content units according to the unit filters + _id in returned by query to repo units. If this is too large, mongo will fail with BSON document too large error. This commit changes the approach of querying the db. Db is queried for unit_ids in batches to void sending too big query. As resulted units are yield from the method, there won't be any noticable difference outside of this method
