SET command supports EX and PX parameters to configure the key TTL. (http://redis.io/commands/SET)

It would be nice if the GETSET command also support those parameters, this way we could SET and configure the TTL in the same command. (http://redis.io/commands/GETSET)

What do you guys think about it? @antirez
