Increase connection timeouts for Redis
Increase connection timeouts for Redis

When using py-redis for connecting to Redis via HAProxy the connection
is being closed even when alive by HAProxy. Unfortunately this is a know
issue on py-redis side (see [1]). This patch increases connection timeouts
to not pollute (for example) Gnocchi [2] logs with reconnect tracebacks every
2 minutes.
