RxJava2: Create an examples handing backpressure

[marcinkunert]

Since we soon will have RxJava2 here (#83) it would be nice to have examples that handle backpressure. Do you have any ideas for good examples?

yeah i've been thinking about this. Couple of points:

• By default we should be using Flowables everywhere as good Rx citizens. Using Flowables inherently add the notion of backpressure but we obv. don't call it out explicitly.
• That being said the pagination example, has a high likelihood of running into a BackPressure exception, which is why that's been handled there
• the problem with having an example just demoing BackPressure is that it doesn't go in the spirit of actual "examples". it's more a demo of an implementation detail (which is fine and a great thing to know) but might have to stick to keeping this repo as a "learn Rx by example" vs just "learn Rx"

if that makes sense.
