Implement filtering without using relay

**Is your feature request related to a problem? Please describe.**
Trying to implement filtering to graphene django, but i don't use Relay (Apollo). And would like the feature to be implemented without having to lock into using relay.

**Describe alternatives you've considered**
Currently have to follow this example: https://www.howtographql.com/graphql-python/7-filtering/

**Additional context**
Would love to know if anyone who is using graphene at scale and how they are filtering queries if they aren't using relay in the stack. Thanks!
