the images are being centralized into the agnhost image, reducing
the number of images that have to be pulled and used.
This PR replaces the usage of the following images with agnhost:
- mounttest
- mounttest-user
Additionally, removes the usage of the mounttest-user image and removes
it from kubernetes/test/images. RunAsUser is set instead of having that image.

of the Logf inside the framework package. This will help with
import size/cycles when importing the framework or subpackages.
**What this PR does / why we need it:** This PR adds [sig-auth] prefix to
workload e2e tests in accord to requirements of adding a SIG dashboard
to testgrid. Refer PR #48781 for guidelines.
