Adds termination hook in reboot test for debugging
From #33405 and #36230.
Logs the SSH command issued for dropping inbound / outbound traffic to file and dump it out when test ends.
The first `sudo iptables -t filter -nL` is called to confirm the rules are injected. The second `sudo iptables -t filter -nL` is to check whether the rules get clobbered. Adds `date` in between to check time frame.

[kubeadm] use iteration instead of recursion in function
**What this PR does / why we need it**:
before this PR, function `attemptToUpdateMasterRoleLabelsAndTaints` recursively call itself. there are some defeats in it:
1. potential stack overflow.
2. unnecessary extra `json.Marshal` calls.
3. unnecessary extra `client.Nodes().List` calls.
this PR rewrite `attemptToUpdateMasterRoleLabelsAndTaints` function, use iterate instead of recursion.
so these 3 defeats the metioned above are gone.

kubelet: don't reject pods without adding them to the pod manager
kubelet relies on the pod manager as a cache of the pods in the apiserver (and
other sources) . The cache should be kept up-to-date even when rejecting pods.
Without this, kubelet may decide at any point to drop the status update
(request to the apiserver) for the rejected pod since it would think the pod no
longer exists in the apiserver.
This should fix#37658

build: clean platform envs to prevent cross-contamination
**What this PR does / why we need it**: As I described in https://github.com/kubernetes/kubernetes/issues/37079#issuecomment-263733509, we are leaking platform compilation envs between build stages for different platforms in the non-parallel dockerized cross build. This PR uses a subshell for the non-parallel build, more closely matching the parallel build.
This also adds some logging, which had it existed previously, may have made the bug more immediately obvious.

remove checking mount point in cleanupOrphanedPodDirs
To avoid nfs hung problem, remove the mountpoint checking code in
cleanupOrphanedPodDirs(). This removal should still be safe because it checks whether there are still directories under pod's volume and if so, do not delete the pod directory.
Note: After removing the mountpoint check code in cleanupOrphanedPodDirs(), the directories might not be cleaned up in such situation.
1. delete pod, kubelet reconciler tries to unmount the volume directory successfully
2. before reconciler tries to delete the volume directory, kubelet gets retarted
3. since under pod directory, there are still volume directors exist (but not mounted), cleanupOrphanedPodDIrs() will not clean them up.
Will work on a follow up PR to solve above issue.

Fix photon controller plugin to construct with correct PdID
**What this PR does / why we need it**:
This PR is to fix a mismatching of unmount path in photon volume plugin, which is resulted from the assigning volume spec name to persistent disk ID. Without this path, unmounting process is stalling in reconciler when a pod is deleted. Restart the same pod will see a mount failure because the previous unmounting is still going on.
The input variable of function ConstructVolumeSpec is the volume spec name instead of persistent disk ID. Previously the function directly construct new volume spec by assigning volume spec name to persistent disk ID, which will result in mismatching of mount path. The fix will find the pdID according to mount path and construct volume spec with the correct pdID.
I have tested the patch with back-to-back pod creation/deletion and mounting/unmounting of photon persistent disk volume source performs normal now.
This need to be cherry-picked to 1.5 release branch.

Collect logs for dead kubelets too
Collect logs via journalctl if journalctl is installed, rather than only if
kubelet.service is running. The old way resulted in us losing logs any
time the kubelet was failing. This, of course, breaks on a node if
someone decided to install journalctl but not use it. But that is not
the case on any of the images used by cluster-level tests at present.
^^^^FYI @Random-Liu not sure if `which journalctl` implies that journalctl is actually used on all of the nodes we test in the node-e2e suites. This may be of consequence if we move to using `cluster/log-dump.sh` to scrape logs for node-e2e.
P0 because this is somewhat in the way of debugging https://github.com/kubernetes/kubernetes/issues/33882

When --grace-period=0 is provided, wait for deletion
The grace-period is automatically set to 1 unless --force is provided, and the client waits until the object is deleted.
This preserves backwards compatibility with 1.4 and earlier. It does not handle scenarios where the object is deleted and a new object is created with the same name because we don't have the initial object loaded (and that's a larger change for 1.5).
Fixes#37117 by relaxing the guarantees provided.
```release-note
When deleting an object with `--grace-period=0`, the client will begin a graceful deletion and wait until the resource is fully deleted. To force deletion, use the `--force` flag.
