Slack notification support for jobs and pods from other operators

[ssvinoth22]

What would you like to be added:
Currently, slack notifications support only for deployments, daemonset and statefulset only... need to integrate with jobs and pods.
Why is this needed:
We are using custom CRD's which create pods/jobs directly.
ex: tekton pipeline which creates pod directly there won't be any Deployment, Daemon set & Statefulset operations. So we need to integrate slack notifications on pods operations too.
