refactor: add support for meta in @link

[tusharmath]

Link doesn't support for additional meta information with the URLs. Let's add it, for eg:

schema @link(
  src: "http://products:4000",
  type: SubGraph,
  meta: { 
    description: "Product service subgraph", 
    version: "1.2.0", 
    environment: "production"
  }
){
  query: Query
}

Technical Requirements

• Meta should accept any JSON scalar.
• Add concise tests for meta
