Disconnects on timeouts

[SS-TruMinds]

Hello,

While using async APIs we notice link disconnects after command timeout, and understand this is because of the existing implementation of redisAsyncHandleTimeout.

This is a request to make this timeout behavior command specific, instead of clearing all the outstanding callbacks & closing the connection with the server.

Thank you.

This would be a nontrivial change, but I do think it's worth exploring.
