Update redis-protocol 0.4 to 0.5

[rukai]

• The "decode-mut" feature is now under the "bytes" feature
• A bunch of methods and types were renamed
• the Redirection type + to_redirection method were removed, they are quite simple so I just reimplemented them in RedisSinkCluster.
• bytes-utils is now reexported within redis-protocol, since we only use that for interacting with redis-protocol, we now use the reexport instead of bytes-utils directly.
