feature request for Transform: RemoveObjectFieldsWithoutDirective

[cnwangjie]

Is your feature request related to a problem? Please describe.

I want to slitch my graphql schema to some different subset. And I found there is a transform that named RemoveObjectFieldsWithDirective. I think that's what I need. But in my case, I want to pick only a few schema in it.

Describe the solution you'd like

There are already RemoveObjectFieldsWithDirective. We just need to implement RemoveObjectFieldsWithoutDirective.
