yogananth-subramanian 2111bab9a4 Pod ingress network shaping Chaos scenario 
The scenario introduces network latency, packet loss, and bandwidth restriction in the Pod's network interface. The purpose of this scenario is to observe faults caused by random variations in the network.

Below example config applies ingress traffic shaping to openshift console.
````
- id: pod_ingress_shaping
  config:
    namespace: openshift-console   # Required - Namespace of the pod to which filter need to be applied.
    label_selector: 'component=ui' # Applies traffic shaping to access openshift console.
    network_params:
        latency: 500ms             # Add 500ms latency to ingress traffic from the pod.

yogananth-subramanian 8806781a4f Pod network outage Chaos scenario 
Pod network outage chaos scenario blocks traffic at pod level irrespective of the network policy used.
With the current network policies, it is not possible to explicitly block ports which are enabled
by allowed network policy rule. This chaos scenario addresses this issue by using OVS flow rules
to block ports related to the pod. It supports OpenShiftSDN and OVNKubernetes based networks.

Below example config blocks access to openshift console.
````
- id: pod_network_outage
  config:
    namespace: openshift-console
    direction:
        - ingress
    ingress_ports:
        - 8443
    label_selector: 'component=ui'

Naga Ravi Chaitanya Elluri bc863fa01f Add support to check for critical alerts 
This commit enables users to opt in to check for critical alerts firing
in the cluster post chaos at the end of each scenario. Chaos scenario is
considered as failed if the cluster is unhealthy in which case user can
start debugging to fix and harden respective areas.
