[Cache] Ask for adding the fourth optional parameter of the RedisAdapter with explanations and examples

[lkolndeep]

Hello folks,

I noticed that in the documentation of the RedisAdapter: Redis Adapter Doc, there is no mention of the fourth optional parameter of this adapter which is the marshaller.

It could be nice to add this in the RedisAdapter documentation with explanations and some examples too.

Thanks in advance,

Regards,
