Quite a few images are only used a few times in a few tests. Thus,
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.
Use the same pattern everywhere in the e2e test
harness, use busybox (from dockerhub) instead
of using the one from k8s.gcr.io registry.

There were already a few tests just using the default framework
namespace instead of creating a new one. Also there are several
testing libraries that use the default framework's default namespace
as well. It's just easier this way.
