yogananth-subramanianandNaga Ravi Chaitanya Elluri b2b5002f45 Pod egress network shapping 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 egress traffic shaping to openshift console.
````
- id: pod_egress_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 egress traffic from the pod.

Naga Ravi Chaitanya Elluri 0eb8d38596 Expand SLOs profile to cover monitoring for more alerts 
This commit:
- Also sets appropriate severity to avoid false failures for the
  test cases especially given that theses are monitored during the chaos
  vs post chaos. Critical alerts are all monitored post chaos with few
  monitored during the chaos that represent overall health and performance
  of the service.
- Renames Alerts to SLOs validation
