Serialization method duplication

[ivasio]

serialization_method logic implemented in #11 results in data duplication left as tradeoff to maximal flexibility and interoperability of homogenous and heterogenous queues. serialization_method is both a part of Redis key (task id) an is a property of Queue (Queue._serialization_method). This data duplication could be avoided

What exactly do you mean by "maximal flexibility and interoperability of homogenous and heterogenous queues"?
