Experimenting with Schedulers.currentScheduler()

The things this would need to solve before being production worth are:

1. Preferably hook into some abstract class so that each Scheduler doesn't need to correctly hook up the notifications.

2. What do we do when not in a Scheduler? Use the trampoline?

3. Handle nested Schedulers, similar to how Hystrix does it: https://github.com/Netflix/Hystrix/blob/master/hystrix-core/src/main/java/com/netflix/hystrix/Hystrix.java#L90

Closing out as not ready to pursue this.
