Add a Kubernetes Events source

[joshgav]

In addition to resource-related events as described in #36, Kubernetes provides a stream of Events which contain info about cluster and workload state and changes. Some details here: https://www.cncf.io/blog/2021/12/21/extracting-value-from-the-kubernetes-events-feed/

Many of those events are great candidates for alerts and remediation via Ansible.

Could you create a Kubernetes "Events" source too? Thanks!
