The "Saturate" phase of StatefulSet e2e tests verifies orderly startup
by controlling when each Pod is allowed to report Ready.
If a Pod unexepectedly goes down during the test, the replacement Pod
created by the controller will forget if it was already allowed to
report Ready.
After this change, the signal that allows each Pod to report Ready is
persisted in the Pod's PVC. Thus, the replacement Pod will remember that
it was already told to proceed to a Ready state.
This reverts commit f4afdecef8, reversing
changes made to e633a1604f.
This also fixes a bug where Kubemark was still using the core api scheme
to manipulate the Kubelet's types, which was the cause of the initial
revert.

This PR adds iSCSI initiatorname parameter to ISCSIVolumeSource
to enable automatic configuration of initiator name per volume.
This would allow for more fine grained configuration, and remove
the need to configure the initiator name on the host by
administrator.

kubeadm: Adds dry-run support for kubeadm using the `--dry-run` option
**What this PR does / why we need it**:
Adds dry-run support to kubeadm by creating a fake clientset that can get totally fake values (like in the init case), or delegate GETs/LISTs to a real API server but discard all edits like POST/PUT/PATCH/DELETE

MakeEventRecorder function cleanup
delete KubeletConfiguration arg since it is unused
fixes#50969
```release-note
NONE
```
During TestCreateWithNonExistentOwner, when creating a pod with a
non-existent owner, assume it's possible the pod will be deleted before
we start checking for the pod's existence. Assuming that the pod still
exists immediately after Create returns is flaky if the GC reacts very
quickly.
In 6c7245d464, code was added to
bail out if the directory that cadvisor monitored did not exist.
However, this breaks the earlier assumption that kubelet created
directories when needed in pkg/kubelet/kubelet.go's setupDataDirs()
method. setupDataDirs() happens much later, so basically kubelet
exits now.
So since cadvisor really needs this directory, let us just create
it

Default NODE_OS to gci on GCE installs
Looking at https://github.com/kubernetes/test-infra/tree/master/jobs,
any job with "cvm" in the name explicitly sets this variable, so I hope
it is only the default.
**Release note**:
```release-note
Change GCE installs (kube-up.sh) to use GCI/COS for node OS, by default.

Use CollisionCount for collision avoidance in StatefulSet controller
**What this PR does / why we need it**:
This PR uses the newly added `CollisionCount` in `StatefulSetStatus` for name collision avoidance when the `StatefulSet` controller creates `ControllerRevision`s. The `CreateControllerRevision` method of the `ControllerHistory` interface was augmented to use a user-specified `collisionCount` instead of the internal probe that always starts with 0. The `StatefulSet` controller uses the `CreateControllerRevision` to create `ControllerRevision`s and when it calls it, it passes in the `CollisionCount` of the `StatefulSet` it manipulates.
