Remove ShardedJedis, and rearrange Pipeline to reflect

* Remove ShardedJedis and relevant classes, methods
** also remove unit tests / benchmark tests
* Rearrange Pipeline to reflect removing ShardedJedis …
** We don't need to separate single key and multi keys operation
*** cause JedisCluster can't use Pipeline by nature
** Rename interfaces to respect naming convention
** and so on...
