[Test]: Add tc to detect drop of outbound traffic as network failure in glusterd
Test Steps: 1) Create a volume and start it. 2) Add an iptable rule to drop outbound glusterd traffic 3) Check if the rule is added in iptables list 4) Execute few Gluster CLI commands like volume status, peer status 5) Gluster CLI commands should fail with suitable error message Change-Id: Ibc5717659e65f0df22ea3cec098bf7d1932bef9d Signed-off-by: nik-redhat <nladha@redhat.com>
