graphiql should always send operation to router

[n1ru4l]

Graphiql on the gateway prevents me from executing invalid operations, they are never sent over http as graphiql validates first and raises an exception. Sometimes it is useful to do that to see how the gateway behaves without having to move to curl or another tool. Can we change it (even in yoga) to always send to the server and ignore graphiql?
