Make log audit backend configurable in GCE
This PR will allow to enable audit logging batching by default in e2e tests, after https://github.com/kubernetes/kubernetes/pull/60739 is merged. This is an important step to prevent a regression in scale tests.

[e2e service] Move apiserver restart validation logic into util
**What this PR does / why we need it**:
Follow up of #60906, on GKE apiserver pod is invisible on k8s, hence test is failing.
This PR bakes the restart validation logic into the util function instead so it could be env-awared.

Fixes#60761

There is a race in predicateAdmitHandler Admit() that getNodeAnyWayFunc()
could get Node with non-zero deviceplugin resource allocatable for a
non-existing endpoint. That race can happen when a device plugin fails,
but is more likely when kubelet restarts as with the current registration
model, there is a time gap between kubelet restart and device plugin
re-registration. During this time window, even though devicemanager could
have removed the resource initially during GetCapacity() call, Kubelet
may overwrite the device plugin resource capacity/allocatable with the
old value when node update from the API server comes in later. This
could cause a pod to be started without proper device runtime config set.
To solve this problem, introduce endpointStopGracePeriod. When a device
plugin fails, don't immediately remove the endpoint but set stopTime in
its endpoint. During kubelet restart, create endpoints with stopTime set
for any checkpointed registered resource. The endpoint is considered to be
in stopGracePeriod if its stoptime is set. This allows us to track what
resources should be handled by devicemanager during the time gap.
When an endpoint's stopGracePeriod expires, we remove the endpoint and
its resource. This allows the resource to be exported through other channels
(e.g., by directly updating node status through API server) if there is such
use case. Currently endpointStopGracePeriod is set as 5 minutes.
Given that an endpoint is no longer immediately removed upon disconnection,
mark all its devices unhealthy so that we can signal the resource allocatable
change to the scheduler to avoid scheduling more pods to the node.
When a device plugin endpoint is in stopGracePeriod, pods requesting the
corresponding resource will fail admission handler.
Created a scheme that only understands admission/v1beta1 and use it to
encode/decode admissionReviews.
Also made the NegotiationSerializer setup static

Rollback etcd server version to 3.1.11 due to #60589
Ref https://github.com/kubernetes/kubernetes/issues/60589#issuecomment-371171837
The dependencies were a bit complex (so many things relying on it) + the version was updated to 3.2.16 on top of the original bump.
So I had to mostly make manual reverting changes on a case-by-case basis - so likely to have errors :)

Create fake /etc/hosts for conformance test
**What this PR does / why we need it**:
"KubeletManagedEtcHosts should test kubelet managed /etc/hosts file"
conformance test fails in the CI's Docker-In-Docker environment.
This test mounts a /etc/hosts file and checks if "# Kubernetes-managed
hosts file." string is present or not under various conditions. The
specific failure with DIND happens when the /etc/hosts picked up
from the box where e2e test are running already has this string. This
happens because our CI runs on kubernetes and the e2e tests are running
in a container that was started on kubernetes (and hence already has
that string)
To avoid this situation, we create a new /etc/hosts file with known
contents (and does not have the "# Kubernetes-managed hosts file."
string)
