Hello.
For spout, it isn't acceptable for reliable data source because during
failure it'll lose some tuples.
(Actually Redis cannot act as reliable message queue, so I think it isn't
good to implement spout for Redis.)
For bolt, every bolt should react based on tuple from spout or other bolt,
so pub/sub seems not fit this case.
