Introduce JedisInvoker.

We now use JedisInvoker to call Jedis and Pipeline methods for synchronous, pipelining, and transactional execution models. JedisInvoker captures the method invocation as functional utility and allows conversion of results:

Long result = invoker.just(BinaryJedis::geoadd, MultiKeyPipelineBase:geoadd, key, point.getX(), point.getY(), member);

Closes #1951
