Support all issue filters as negated issue filters in GraphQL API
Proposal
As part of #300115 (closed) all negated issue filters supported by the IssueFinder will be added to the GraphQL API as arguments.
From !58154 (comment 546592356) we'd like to discuss if all other non-negated issue filters should be supported as negated issue filters. This would require changes in the Issue finder and not only on the GraphQL interface.
If we do add support for this in GQL, should we also support the new filters in the REST API and Rails controllers?
