Closes #451

Looks good, just a minor comment. But, I'm open to this solution as well.

I think this should just be the global default Link. Maybe something like:

public Link DefaultRelationshipLinks { get; set;} = Link.All

[milosloub]

That makes sense with Link.All. I thought about this more and got following:
a) we can expose new property on JsonApiOptions "DefaultRelationshipLinks" (instead of DisableSelfAndRelatedLinks )
b) we can use present property ResourceGraphBuilder on JsonApiOptions, set it's DocumentLinks and than check this property while building resource in DocumentBuilder.cs.

Second solution might be breaking change, if you are developer who set it like this before. But I can´t imagine why anyone would do this.
What do you think?

[jaredcnance]

I think option "a" would be better so we can distinguish between the resource level links and the relationship links. That being said, we should probably move the ResourceGraphBuilder.DocumentLinks into JsonApiOptions as well. Ideally, since auto discovery has landed, ResourceGraphBuilder shouldn't be necessary for most applications.

[milosloub]

For now I did it like options.DefaultRelationshipLinks. I didn't move DocumentLinks. If you want to do it at once - this will lead to change unit test Page_Links_Can_Be_Disabled_Globally.
