AfterEffects: exposing Deadline pools fields in Publisher UI (#6079)

* OP-6421 - added render family to families filter

As published instances follow product type `render` now, fields wouldn't be shown for them.

* OP-6421 - updated documentation

* OP-6421 - added hosts filter

Limits this with higher precision.
