This commit adds support to create zone outage in AWS by denying both
ingress and egress traffic to the instances belonging to a particular
subnet belonging to the zone by tweaking the network acl. This creates
an outage of all the nodes in the zone - both master and workers.
Current Kraken integration with Cerberus monitors the cluster as well as the
application health post chaos and pass/fails if they are not healthy after chaos.
This commit adds ability to monitor the user application health during the chaos
and fails the run in case of downtime as it's potentially a downtime in case of
customers environment as well. It is especially useful in case of control plane
failure scenarios including API server, Etcd, Ingress etc.
