Evicted trigger

[Avi-Robusta]

This is only for standard evictions due to node pressure (when you run kubectl get pods and you see the status as evicted)

This is not for:

1. Pod evictions due to node taint for example :

   kubectl taint nodes NODE_NAME key1=value1:NoExecute

2. Pod evections due to directly calling the eviction api for example

   kubectl proxy --port=8080  &
   POD_TO_EVICT="POD_NAME"
   curl -k -v -XPOST  -H "Accept: application/json" -H "Content-Type: application/json" "http://localhost:8080/api/v1/namespaces/default/pods/${POD_TO_EVICT}/eviction" --data '{"kind":"Eviction","apiVersion":"policy/v1beta1","metadata": {"namespace": "default","name": "'"${POD_TO_EVICT}"'"}}'

Both have different status's and fields in the pod yaml so they are not in this trigger, they can be added in the future.

Here is an example playbook

customPlaybooks:
- triggers:
  - on_pod_evicted: {}
  actions:
  - create_finding: #
      title: "Pod $name in namespace $namespace was Evicted"
      aggregation_key: "PodEvictedTriggered"
