Improve Redis failure modes (#29405)

While investigating code paths during
Redis downtime, I found out that the library
by default retries indefinitely for read commmands.

This leads to it being stuck in a loop
while trying to read anything from Redis.
We fix that by disabling retry.

Secondly, we adjust the ConnWriteTimeout
value slightly from its default of 10s
which is a bit too high for normal working
conditions.
