Use a global dataloader for the batch load function

[scf4]

In my personal fork of redis-dataloader I use a final dataloader instance to coalesce redis mget calls. It's super helpful, saving ~3-4 round trips per request.

Side note, if you'd be interested I'd like to merge my code into yours by adding node-redis support and passing tests, and then I could help with maintenance of the project.

Hey ok that sounds great thanks!

One thing is I need this library to be compatible with at least node 6. I don't think the await/async stuff is supported until node 7?

Maybe I could put in some babel transpilation, I was thinking about adding support for flow types anyways.

any async/await support in the works or suggestions on a library that is similar? @DubFriend @scf4
