Support DGS-generated types for Relay pagination (@connection directive)

[seanf]

It would be nice if the plugin could dynamically generate/understand the Connection/Edge/PageInfo types which are generated by the relay pagination feature of DGS. At present, any schema which refers to the generated Connection types shows errors, and autocomplete doesn't work when composing queries which need Connection, Edge or PageInfo types.

I see, that is valid and I think will be a concern for any types that we will dynamically generate. Will fix.

This would be awesome to have!
