PS10: 
Patchset 10, white space and typo in documentation.

Rational for separate res_redisd;

1. One module to deal with configs, threadsafe connect/disconnect, socket file descriptor leaks. 
2. Code deduplication. func_db_redis and res_redis_device_state would have all of res_redisd in each module.

I originally had one monolithic res module with all funcs and resources calling 1 common function which is now in res_redisd, to handle connection setup(with optional AUTH and DB selection), retry/reconnect, the Redis operation, then teardown, with no file descriptor leaks, and was threadsafe.

But not to the extent to have each function use native hiredis function calls to setup a socket to redis, reconnect/retry if that failed, do the redis operation, then teardown the socket.
