Proper casting to interface instead of unextendable redisClient.

[joelharkes]

We have a problem extending the RedisClient (we are making a prefixed redis client) because the methods are not virtual

we subclassed it anyways and just overwrote the interface methods. but the problem is that RedisClientManagerCacheClient.cs hard casted it to RedisClient instead of the appropriate interface leaving us with not possibility to overwrite this method. I fixed the usages in this PR.

Could you please merge and create a new Core release of servicestack soon?

Did this compile for you? This broke our build.

RedisClientManagerCacheClient.cs(187, 53): error CS1061: 'IRemoveByPattern' does not contain a definition for 'Keys' and no extension method 'Keys' accepting a first argument of type 'IRemoveByPattern' could be found (are you missing a using directive or an assembly reference?)
RedisClientManagerCacheClient.cs(189, 37): error CS1061: 'IRemoveByPattern' does not contain a definition for 'Del' and no extension method 'Del' accepting a first argument of type 'IRemoveByPattern' could be found (are you missing a using directive or an assembly reference?)

Let me know if this is a quick fix, otherwise I'll need to revert these changes.
