Implement flexible exposed Filtering on Edges

This feature make sense to me since could provide expected capabilities if migrating from v3.x

The current filtering needs to be thrown out and re-done, and tap into the field conditions better.

Replace the lot by building around the graphql producer "entity query"
https://github.com/drupal-graphql/graphql/blob/8.x-4.x/src/Plugin/GraphQ...

And implement cursors on-top of that to manage the offset.

This is a worth while feature request. I've had to point people at Views multiple times. But sometimes, people want cursors.
