When we built the added the original interactive refactors support, we supported the client telling the server which field kinds it can prompt for, so that if there were questions the client didn't support that did not have default values, the refactor could be hidden.
However, we only implemented one such refactor (Move to File) and the only field (destination URI) has a default value, so the client capabilities never have any effect.
Since we're replacing this support with the new "Interactive Forms" and don't intend to create any new refactors using the old system, this code is all redundant and therefore can be deleted.
