Clean up diskLooksUnformatted literal
**What this PR does / why we need it**:
#16948 moved the `formatAndMount` function to mount_linux.go, but `diskLooksUnformatted` does not necessarily need to appear in mount_unsupported.go
#31515 Renames `diskLooksUnformatted` to `getDiskFormat`, but did not update the comment
This is to do the small cleanup.

flexvolume: remove a mount directory in a error case
**What this PR does / why we need it**:
flexVolumeMounter.SetUpAt creates a directory, where a volume has to be
mounted, and we have to remove this directory in a error case. Otherwise
we see errors like this:
Orphaned pod 673b66d9-70f7-11e7-a5fa-525400307392 found, but volume paths are still present on disk

kubelet: fix inconsistent display of terminated pod IPs
PLEG and kubelet race when reading and sending pod status to the apiserver. PLEG
inserts status into a cache, and then signals kubelet. Kubelet then eventually
reads the status out of that cache, but in the mean time the status could have
been changed by PLEG.
When a pod exits, pod status will no longer include the pod's IP address because
the network plugin/runtime will report "" for terminated pod IPs. If this status
gets inserted into the PLEG cache before kubelet gets the status out of the cache,
kubelet will see a blank pod IP address. This happens in about 1/5 of cases when
pods are short-lived, and somewhat less frequently for longer running pods.
To ensure consistency for properties of dead pods, copy an old status update's
IP address over to the new status update if (a) the new status update's IP is
missing and (b) all sandboxes of the pod are dead/not-ready (eg, no possibility
for a valid IP from the sandbox).

Validate that cronjob names are 52 characters or less
**What this PR does / why we need it**:
Right now when you create a cronjob with a name longer than 52 characters, creation will succeed but the cronjob controller will create Job objects with names longer than 63 characters. Jobs cannot have names longer than 63 characters, so the cronjob will never be able to run any jobs.
