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.

issue: #31362
When no nvidia device was attached, the -ne check had a syntax error:
sh: -ne: argument expected
This resulted in 'Success' being echoed and the test passing incorrectly.
This was found while debugging issue #47216

Kubelet: rename cri package name to pkg/kubelet/apis/cri/v1alpha1/runtime
**What this PR does / why we need it**:
We have moved CRI from api/v1alpha1/runtime to apis/cri/v1alpha1, which changed the package name of CRI. This would cause a significant problem: old-versioned runtime (based on CRI in v1.6) doesn't work with latest kubelet v1.7, and vice versa.
This PR renames cri package name to `pkg/kubelet/apis/cri/v1alpha1/runtime` for fixing the problem.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*:
fixes#47012
**Special notes for your reviewer**:
Should be included in v1.7.
**Release note**:
```release-note
CRI has been moved to package `pkg/kubelet/apis/cri/v1alpha1/runtime`.

Move the nvidia installer to the beginning.
When the installer runs for the first time, it disables loadpin and restarts
the node. So, it is better to run it in the beginning so that we can avoid
redoing the later steps. One of the later steps include downloading a tar file
and untarring it. Doing that only once saves around 1m30s in test runtime for
the gci image.

This PR adds two features:
1. add support for isolating the emptyDir volume use. If user
sets a size limit for emptyDir volume, kubelet's eviction manager
monitors its usage
and evict the pod if the usage exceeds the limit.
2. add support for isolating the local storage for container overlay. If
the container's overly usage exceeds the limit defined in container
spec, eviction manager will evict the pod.

Add local storage (scratch space) allocatable support
This PR adds the support for allocatable local storage (scratch space).
This feature is only for root file system which is shared by kubernetes
componenets, users' containers and/or images. User could use
--kube-reserved flag to reserve the storage for kube system components.
If the allocatable storage for user's pods is used up, some pods will be
evicted to free the storage resource.
This feature is part of local storage capacity isolation and described in the proposal https://github.com/kubernetes/community/pull/306
**Release note**:
```release-note
This feature exposes local storage capacity for the primary partitions, and supports & enforces storage reservation in Node Allocatable

[Flaky PR Test] Fix summary test
fixes issue: #46797
As we can see in the [example failure build log](https://storage.googleapis.com/kubernetes-jenkins/logs/ci-kubernetes-node-kubelet/4319/build-log.txt), the summary containers are pinging google 100s of times a second. This causes the summary container to be killed occasionally, and fail the test. The summary containers are only supposed to ping every 10 seconds according to the current test. As it turns out, we were missing a semicolon, and were not sleeping between pings. For background, we ping google to generate network traffic, so that the summary test can validate network metrics.
This PR adds the semicolon to make the container sleep between calls, and decreases the sleep time from 10 seconds to 1 second, as 1 call / 10 seconds did not produce enough activity.

Support validating package versions in node conformance test
**What this PR does / why we need it**:
This PR adds a package validator in node conformance test for checking whether the locally installed packages meet the image spec.
**Special notes for your reviewer**:
The image spec for GKE (which has the package spec) will be in a separate PR. Then we will publish a new node conformance test image for GKE whose name should use the convention in https://github.com/kubernetes/kubernetes/issues/45760 and have `gke` in it.
**Release note**:

Summary Test looks at pods that have containers that restart.
Occasionally, the node can report extra containers that had been restarted through the summary API.
This test change tests a pod that restarts, and hopefully should allow us to reproduce and debug this behavior.

Move docker validation test to separate project.
Docker validation test is leaking VMs because new docker version `DOCKER_VERSION=17.05.0-c` totally breaks the new gci image `GCE_IMAGES=gci-test-60-9579-0-0` with the `gci-docker-version` metadata specified.
The test successfully created the instance, but timed out when checking VM aliveness, and leaked the VM.
I've cleaned up all leaked VMs. This PR moves docker validation node e2e test into a separate project to not influencing other node e2e test.
@kewu1992 We should fix the docker automated validation test.

Log age of stats used for evictions during eviction tests
I recently added prometheus metrics for the age of the metrics used for evictions #43031. It would be nice to surface these during eviction tests, so I can better assess how old stats are, and whether or not the age of stats causes extra evictions.
This isnt super-high priority, and can be done after code-freeze, since it is a testing improvement. Feel free to take a look whenever either of you has time.

Ensure ordering of using dynamic kubelet config and setting up tests.
This PR simply places the body of the eviction test within its own context. This ensures that the kubelet config is set before the pods are created, and that the kubelet config is reverted only after the pods are deleted.
