Replacing GraphiQL

[DevanB]

This issue pertains to:

• GraphQL Playground

After some light investigation, in order to replace GraphiQL with graphql-playground, a few options for pre-filling are necessary. Those are:

• endpointURL: the relative/absolute URL where graphql-playground will make queries to
• query: the GraphQL query to pre-fill
• variables: a JS object of variables to pre-fill
• operationName: the operationName to pre-fill
• result: the result of the query to pre-fill

Also, default settings (theme etc.) should be added to the middleware options.

I'd love to see the replication of the fetcher prop that can accept an observable!

This is now also tracked in #487.
