making Jedis compatible with CDI
we can't pass null because it will throw an exception. Using localhost instead
changing default constructor to use default host and port (localhost)
using super instead of this to keep the code style
Merge branch 'making_jedis_pool_cdi_compatible' of https://github.com/nykolaslima/jedis into nykolaslima-making_jedis_pool_cdi_compatible
only Connection should take care of default host, port
Unify style
