Subject: [PATCH] Adding onReadyStateChange callback to setVariables

`this.props.relay.setVariables` takes an optional callback that's not currently represented in the types. Just adding that.

See this answer on StackOverflow for a high-level overview:
http://stackoverflow.com/questions/35471836/loading-indicator-after-this-props-relay-setvariables-triggered-fetch

And the docs have more detailed information about what the callback provides:
