Possible to filter nodes by translation?

HI @jmolivas
Thanks for your module it was helpful for my personal project,
I have figured out a solution to make the module translatable, basically, I implemented 2 new producers in the ContentTypeSchemaExtension that accept the language parameters, so the GraphQl would be :

query ($path: String!, $language: String!){
  nodeByPathLang(path: $path, language: $language) {
    ... on NodeArticle {
      __typename          
      id         
      title          
      path        
      tempKeyWorldMeta          
      summary{         
        value          
      }         
      author {           
        displayName
      }          
      body {
        processed         
      }          
      status         
      created        
    }      
  }    
}

That means big changes in the code, and non-backward compatibilities, maybe I missing something, but I didn't find a way to implement a new ContentTypeLangSchemaExtension class that accepts lang parameters, I have an error "ArticleNode type already declared"
It would be helpful if I have some guidance for that,
I'm on slack, a direct chat will be more effective

In 2.x we van now filter content with views.
But it would be nice to have language it in the router also.

I'll work on this with 2.x.

Added langcode filter to route() query, this ticket is considered fixed for 2.x

2.x beta2+
