Add support to configure batch resolvers

[stevewillard]

It would be great if you could configure field resolvers to batch resolver (and configure what that number is).

PR is welcome.

I am not actively using this module myself, so it is unlikely that I will add new features in the near future myself, but I can still review and merge other contributors' code.
