--------------------------------------------

I think the best way to do it is to use pool for Thrift transports.

> SENTRY-1477 provided a simple connection retry model which is incompatible with the object pool. I think that we can combine the pool model in case of multiple connections by using GenericKeyedObjectPool using server address as a key. When we suspect a disconnect we can clear the whole sub-pool using clear(key).
