This Epic contains JIRAs to implement the Resolver Mappings in the Schema Editor.

The mockups can be found here: https://redhat.invisionapp.com/share/SVMB0QW6MR9#/screens

This dialog allows you to add a request and response resolver to any field in the structure view. Requests resolvers are the traditional GraphQL resolvers that specify how to resolve a given type or property. Response resolvers are handlebars templates that allow you to format the response in a way so that it is usable for GraphQl.
