Specify codec for containers to encode/decode values

[mathieulongtin]

I had a need to store JSON encoded data in a Walrus Hash, so I hand coded a class to do that, but I was wondering if there would be more interest for something like this.

Example:

>>> hash = redisconnection.Hash(codec=json)
>>> hash["hello"] = dict(place="world", greeting="hey")
# Dict is stored as a JSON
>>> hash["hello"]
{"place": "world", "greeting": "hey"}
>>>

So my question:
Is there any interest for a PR that would implement that for all containers?

The codec would be any module or object that implements both loads and dumps function/method.

Probably gonna pass on this for now, but thank you for your suggestion.
