Closes #967

Adding support for memcached binary protocol as described in
https://github.com/memcached/memcached/blob/master/doc/protocol.txt.

Protocol can be set via memcached.protocol property of YCSB memcached workload. if specified
protocol must be "binary" or "text". If unspecified text version is used.

* Expand on the README, covering table creation and best-practices for table config
* Avoid unnecessary Text object creations (in loops and instead of byte[] usage)
* Use a ConcurrentHashMap to better match the DB API
* Fix error messages and always call printStackTrace() on exceptions
* Use BATCHED_OK instead of OK in insert() (more correct)

The original Aerospike interface layer was created when the REPLACE_ONLY option was not available.  This provides a policy more in line with the policies that other databases have implemented their interface layers.
