Cannot customize ThreadFactory in GenericScheduledExecutorService

[ffgiraldez]

Some platform like AppEngine have limitations populating threads and have their own mechanism to do it. with last version (1.1.6 at this moment) it's not posible to use rx-java in gae due to don't exist a mechanism to override via RxPlugin or whatever the ThreadFactory in GenericScheduledExecutorService used in ObjectPool.

In 1.0.X version don't exist that class and ObjectPool(1.0.X) use Schedulers.computation().createWorker instead.
Please add some mechanism to pass our custom ThreadFactory into GenericScheduledExecutorService in order to use last version of rx-java in GAE

See #4173. It would be great if you could check that PR out and see if there isn't anything pre-initializing the GSES if your first action only touches RxJavaHooks.

Closing via #4173.

work like a charm with 1.1.7 using RxJavaHooks instead of RxJavaPlugin thanks a lot @akarnokd
