T8293: Add ability to set timeout for high-availability health-check

Setting a timeout allows VRRP health-check scripts to run longer than the set interval.
Without timeout, keepalived considers the script as failed after interval seconds.
With timeout set higher than interval, the script has more time to complete
before being marked as failed and transitioning VRRP to FAULT state.
