Description

The frontend currently runs all of the queries of the same type in sequence;
i.e. querying the factories and querying the schedds.
This results in very long query times.

Since all of those services are independent, it would make more sense doing it in parallel.

This is biting CMS AnaOps right now... the query times are often in the 7 min range.

Implemented the proposal;
it was pretty simple, and required only minor code changes.

The code is in v3/5691.

BTW: It has a minor conflict with #5579, so I created v3/5579_v2_5691 as well... this one has the conflict solved.

Please review.
