[infinispan-dev] Reactive Streams + RxJava

I was thinking more about [1] and I find that I was going to implement
basically reactive streams. What we have now in github is similar but it
uses a very crude method of blocking the thread to prevent back pressure.
This can then cause severe issues as many users have found out when they
don't close iterator.

Unfortunately reactive streams is just a spec. I am proposing to add RxJava
[2] as a dependency [2] in the core module to provide access to reactive
streams and the various conversion methods. This library adds a bunch of
support for built in back pressure, transformations and much more which
would reduce the amount of code I would need to write substantially.

In regards to timing, I am thinking this is too close for 9.1, so maybe 9.2
or higher.

What do you guys think?
