With this implementation, we are migrating from starboard operator to trivy operator: (#580)

1. We have updated kube_enforcer,kube_enforcer_advanced manifest files with Trivy Operator Resources
2. Updated relevant gen_ke_certs.sh and readme files
3. Upgraded trivy-operator version to  latest (0.28.0)as the existing version has critical vulnerabilities.
