Fix test images
These commits fix volume_io tests for iSCSI and Ceph RBD. Both server images were quite old (Fedora 22), so I updated them to ~~something more stable (CentOS 7) and to newer Ceph (Jewel, 10.2.7).~~ something newer (Fedora 26).
The most important fix is that the test volumes have 120 MB so volume_io test can actually run - the tests put 100MB file to the volume to check its persistence.
When mount containers in #53440 are merged I'll try to run the tests regularly with every PR (or merge) so we catch regressions quickly.

Fixes: #56725
After client pod is stopped we need to wait for a while for kubelet to
unmount and clean up the client pod before we can destroy the server pod.
Killing e.g. iSCSI server too early may result in stale attached device
that cannot be removed.
- create 120MB volume instead of 1MB for volume_io tests
- rebase to Fedora 26
- added compatibility with ext4 and older ceph clients
- unify CephFS and Ceph RBD images.

Prevent webhooks from affecting admission requests for WebhookConfiguration objects
**What this PR does / why we need it**:
As it stands now webhooks can be added to the system which make it impossible for a user to remove that webhook, or two webhooks could be registered which make it impossible to remove each other.
The first commit of this will add a test to make sure webhook deletion is never blocked by a webhook. This test will fail until the second commit is added which will prevent webhooks from affecting admission requests for ValidatingWebhookConfiguration and MutatingWebhookConfiguration objects in the admissionregistration.k8s.io group
- [x] Test that webhook deletion is never blocked by a webhook ([test fails before second commit](https://k8s-gubernator.appspot.com/build/kubernetes-jenkins/pr-logs/pull/59840/pull-kubernetes-e2e-gce/23731/))
- [x] Prevent webhooks from being called on admission requests for [Validating|Mutating]WebhookConfiguration objects
- [x] Document this new behavior maybe in another PR
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Part of fixing #59124 (Verifies that it can remove the broken webhook.)
**Release note**:
```release-note
ValidatingWebhooks and MutatingWebhooks will not be called on admission requests for ValidatingWebhookConfiguration and MutatingWebhookConfiguration objects in the admissionregistration.k8s.io group
```
This is the 2nd attempt. The previous was reverted while we figured out
the regional mirrors (oops).
New plan: k8s.gcr.io is a read-only facade that auto-detects your source
region (us, eu, or asia for now) and pulls from the closest. To publish
an image, push k8s-staging.gcr.io and it will be synced to the regionals
automatically (similar to today). For now the staging is an alias to
gcr.io/google_containers (the legacy URL).
When we move off of google-owned projects (working on it), then we just
do a one-time sync, and change the google-internal config, and nobody
outside should notice.
We can, in parallel, change the auto-sync into a manual sync - send a PR
to "promote" something from staging, and a bot activates it. Nice and
visible, easy to keep track of.

succeeds when Docker is running with SELinux enabled (while the one from
busybox fails.)

note that we don't change the behaviour of kubectl.
For example it won't scale new resources. That's the end goal.
The first step is to retrofit existing code to use the generic scaler.

utils/image/manifest has an additional `arch` parameter, which determines
whether an image ends in `-$ARCH` (like `-amd64`).
All locations that previously had gcr.io urls referenced in costants or inline
have been updated to refere test/utils/image.

What this PR does / why we need it:
This adds an e2e test for aggregation based on the sample-apiserver.
Currently is uses a sample-apiserver built as of 1.7.
This should ensure that the aggregation system works end-to-end.
It will also help detect if we break "old" extension api servers.
