Several changes have been added to this commit:

- Add asking to cluster commands
- Make jedis cluster return connection to original pool
- Add tests for MOVED and ASK cluster responses
- Refactor connection handler to recalculate connections based on slots

This commit makes the first usable version of Jedis along with Redis Cluster
