As per the suggestions, refactor the redis key prefixing to use a custom
redis client that prefixes the keys it uses.

The custom client implementation does not prefix every key by default as
the way of prefixing keys may differ for some redis commands, instead it
lists those keys that will be prefixed. In case of commands, where
multiple keys can be passed as an argument, the custom client defines
where the arg positions are starting and ending for the given command.
