How do you use NodeGraphType to define an Interface

[RehanSaeed]

I would like to use NodeGraphType to implement the NodeInterface type. I'm trying to get my head around why NodeGraphType exists and how to use it. I think it:

1. Implements Interface<NodeInterface>(); for you.
2. Implements the If field for you using Id(x => x.Id) instead of defining it yourself:

this.Field(x => x.Id, type: typeof(NonNullGraphType<IdGraphType>))
    .Description("The unique identifier of the droid.");

3. Registers the type globally, so that given you implement QueryGraphType, lets you resolve any object globally by it's ID.

I've also found a few problems:

1. It assumes that the ID is of type string. Can I use a System.Guid instead?
2. The GetById is not async and does not accept a CancellationToken. Ideally it should have the signature:

Task<Droid> GetById(T id, CancellationToken cancellationToken = default);

Where T is a generic type to allow you to specify the type of the ID. Allowing you to use a Guid.

+1, our FEDs are asking for Relay support now and I'm thinking I'm going to have to implement this since you haven't heard back. Will open source it when I can.
