exclude examples, apimachinery samples, from sast/snyk scan

None of our examples are items that run in any of the images produced
for shared resources csi driver.  They are simply artifact users can employ
when trying out the system, learning what it can do.
Also, the 'vendor/k8s.io/apimachinery/pkg/util/managedfields/pod.yaml' cited
by the scan is a sample from that component as well.  you'll see it creates the pod "some-name" in the default namespace
