Fix flaky cluster-autoscaler e2e
Ref: https://github.com/kubernetes/autoscaler/issues/89
Add pdb to allow cluster-autoscaler to drain nodes with some kube-system components (turns out there can be enough of them to deny scale-down even with 5 healthy nodes). Increased scaleDownTimeout to take into account the time it will take to re-schedule pods running on broken node (this may reset scale-down timer).

Fixed e2e test flake - ClusterDns - should create pod that uses dns
**What this PR does / why we need it**:
String replaced in this test for example pod yaml (dns-frontend-pod.yaml) file is incorrect.
**Which issue this PR fixes** :
fixes#45915
Internal attach/detach controller timers should be configurable and tests
should use much shorter values.
reconcilerSyncDuration is deliberately left out of TimerConfig because it's
the only one that's not a constant one, it's configurable by user.

Fix flaking cluster-autoscaler e2e
Ref: https://github.com/kubernetes/autoscaler/issues/89
Scale-down e2e require 5 healthy nodes to pass reliably, this PR should fix the flaking "should correctly scale down after a node is not needed and one node is broken" e2e.

This just modifies the API and does the minimal plumbing. I can extend this pull or do another to fix the priority problem.

Don't test the debug /logs endpoint on GKE.
GKE will not enable the /logs endpoint in 1.7. I'd like this test to still test the other cluster level endpoints.

Do not add unique label to DaemonSet
**What this PR does / why we need it**:
It's mainly for #46925. DaemonSet controller adds a unique label to DaemonSet, which is unexpected to federation.
The 1st commit addressed #46981 to construct history once and pass it around, so that we can avoid adding that unique label in DaemonSet in the 2nd commit. ~The 3rd commit just reverts the band-aid PR #47103.~

Write reports for each upgrade test
Due to the way Ginkgo runs individual test cases and the level of coordination required for the upgrade tests, they were all run under a single Ginkgo test case. This PR generates and auxiliary report that break out the results of each upgrade test. This is accomplished by:
1) Wrapping `ginkgo.Fail` and `ginkgo.Skip` to get the actual failure or skip messages.
2) Recovering that info in the upgrade test to generate an auxiliary report.
I suggest reviewing commit by commit.

Update GPU e2e tests.
* Use nvidia driver installer from external repo.
That installer decouples itself from COS image version (as long as the
image version is newer than cos-stable-59-9460-60-0).
A separate commit in the test-infra repo will update the cos version
used for this test to cos-stable-59-9460-60-0.
* Use cos-stable-59-9460-60-0 and newer installer for GPU node e2e tests.
This is to enable #47388.

In 1.7, we add controller history to avoid unnecessary DaemonSet pod
restarts during pod adoption. We will not restart pods with matching
templateGeneration for backward compatibility, and will not restart pods
when template hash label matches current DaemonSet history, regardless
of templateGeneration.

Enable Node authorizer and NodeRestriction admission in kubemark
xref https://github.com/kubernetes/features/issues/279
We want to ensure scale testing covers use of the authorizer/admission pair that partitions nodes. This includes enabling the authorizer, which populates a graph of existing nodes and pods.
Kubemark is still running all nodes with a single credential, so a follow-up step is to generate unique credentials per node (or enable TLS bootstrapping) and remove the temporary rolebinding added in this PR so the node authorizer is the one authorizing each call by a hollow node.

Shorten eviction tests, and increase test suite timeout
After #43590, the eviction manager is less aggressive when evicting pods. Because of that, many runs in the flaky suite time out.
To shorten the inode eviction test, I have lowered the eviction threshold.
To shorten the allocatable eviction test, I now set KubeReserved = NodeMemoryCapacity - 200Mb, so that any pod using 200Mb will be evicted. This shortens this test from 40 minutes, to 10 minutes.
While this should be enough to not hit the flaky suite timeout anymore, it is better to keep lower individual test timeouts than a lower suite timeout, since hitting the suite timeout means that even successful test runs are not reported.
