Fix spelling of the word successfully
Auto-generated via:
    git grep -l [Ss]uccesfully  | xargs sed -ri 's/([sS])uccesfully/\1uccessfully/g'

I noticed this when running kube-scheduler with --v4 and it is annoying.
Then manually reverted changed to the vendored bits.

b4b8fdbca3 GC: Fix re-adoption race when orphaning dependents.
The GC expects that once it sees a controller with a non-nil
DeletionTimestamp, that controller will not attempt any adoption.
There was a known race condition that could cause a controller to
re-adopt something orphaned by the GC, because the controller is using a
cached value of its own spec from before DeletionTimestamp was set.

This fixes that race by doing an uncached quorum read of the controller
spec just before the first adoption attempt. It's important that this
read occurs after listing potential orphans. Note that this uncached
read is skipped if no adoptions are attempted (i.e. at steady state).

bd912f50ba statefulset: use pvc lister, replace legacylisters
Use a PVC lister instead of a client when retrieving PVCs.

Replace unit test's use of legacylisters with the generated listers.

4d99b4d825 StatefulSet refactoring and semantics fix
1. pcb and pcb controller are removed and their functionality is
encapsulated in StatefulPodControlInterface.
2. IdentityMappers has been removed to clarify what properties of a Pod are
mutated by the controller. All mutations are performed in the
UpdateStatefulPod method of the StatefulPodControlInterface.
3. The statefulSetIterator and petQueue classes are removed. These classes
sorted Pods by CreationTimestamp. This is brittle and not resilient to
clock skew. The current control loop, which implements the same logic,
is in stateful_set_control.go. The Pods are now sorted and considered by
their ordinal indices, as is outlined in the documentation.
4. StatefulSetController now checks to see if the Pods matching a
StatefulSet's Selector also match the Name of the StatefulSet. This will
make the controller resilient to overlapping, and will be enhanced by
the addition of ControllerRefs.
