Adds supports for grapqhl-ruby 1.9 new runtime

[knshiro]

GraphQL-Ruby 1.9.0 includes a new runtime module which you may use for your schema. Eventually, it will become the default.

Problem is that it doesn't support proc-dependent field features anymore. So this PR creates a Field extension to implement the same feature.

NB: Also adds tests and a travis ci config.

@knshiro May I ask how well this is working for you? I'd like to use it, but I am afraid this repo isn't really being maintained anymore so it may never get merged.

[knshiro]

@jbeker I added tests that I stole from https://github.com/Shopify/graphql-batch/blob/master/test/graphql_test.rb and as you can see here https://travis-ci.org/knshiro/graphql-preload I got all the tests to pass.
I still can't use it in our project though because we are also using https://github.com/exAspArk/graphql-errors and I could not make it work with preload cf https://travis-ci.org/knshiro/graphql-errors

[jbeker]

Thanks for the response @knshiro. I think I will steer clear for now until it gets merged but I don't have high hopes for that.

I see this is more updated, going to try it:

@tjsingleton pretty sure it was only waiting for validation ? Unless there was an issue that was not solved.

While you are here. could you tell us if this gem is still supposed to be supported ?

A friendly bump on that one, right now this is quite a blocker for me. It seems like the solution in this PR should work, definitely using Field Extensions is the way to go.
