recipe/redis: implement promise with redis-cli

This way we don't need to vendor python-redis (so we don't need to
update it for python3 support).

This also change the options in a backward incompatible way:
 - options are now kebab case ( server_bin -> server-bin )
 - a new cli-bin option holding the full path to redis-cli command
 is required to enable promise
