Title: Add support for Apache Zookeeper as a transport

Apache Zookeeper can be used as a message queue as explained in these links.

* https://zookeeper.apache.org/doc/trunk/recipes.html#sc_recipes_Queues
* http://www.cloudera.com/blog/2009/05/building-a-distributed-concurrent-queue-with-apache-zookeeper/

With this module, it is possible to use Apache Zookeeper as a transport with support for priorities. The limitation is that a queue can handle only 2^32 messages. Working on a fix for this.
