…nebs-archive#1544) This PR fixes the liveness probe on cstor-pool container by adding `timeout` setting for command execution(run a command with a time limit). `timeout` will be helpful in a case when the disks are detached from the node and when liveness triggers command(zfs set... command) it will be hung forever and kubelet will not treat them as a failures. Kubelet also retries execute the same command after timeoutSeconds mentioned in the liveness probe. By triggering timeout 120 zfs set io.openebs:livenesstimestamp="$(date +%s)" cstor-<pool_name> will kill the process if it exceeds more than 120 seconds and returns non-zero exit status.
