Fix system container detection in kubelet on systemd
```release-note
Fix system container detection in kubelet on systemd.
This fixed environments where CPU and Memory Accounting were not enabled on the unit
that launched the kubelet or docker from reporting the root cgroup when
monitoring usage stats for those components.
```

Use pause image depending on the server's platform when testing
Removed all pause image constant strings, now the pause image is chosen by arch. Part of the effort of making e2e arch-agnostic.
The pause image name and version is also now only in two places, and it's documented to bump both
Also removed "amd64" constants in the code. Such constants should be replaced by `runtime.GOARCH` or by looking up the server platform
Fixes: #22876 and #15140
Makes it easier for: #25730
Related: #17981
This is for `v1.3`

rkt: Use volumes from RunContainerOptions
This replaces the previous creation of mounts from the `volumeGetter`
with mounts provided via RunContainerOptions.
This is motivated by the fact that the latter has a more complete set of
mounts (e.g. the `/etc/hosts` one created in kubelet.go in the case an IP is available).
This does not induce further e2e failures as far as I can tell.

Add more global options to local-up-cluster.sh
I added a couple more global variables to the `local-up-cluster.sh` script.
The `KUBELET_HOST` environment name make sense to me. If it isn't the best name I will change it.
The `ETCD` ones make sense since they are being used under `hack/lib/etcd.sh`

prevent namespace cleanup hotloop
Found chasing a sentry report. Looks like we hot-loop on namespace deletion failures.

kube-controller-manager: Add configure-cloud-routes option
This allows kube-controller-manager to allocate CIDRs to nodes (with
allocate-node-cidrs=true), but will not try to configure them on the
cloud provider, even if the cloud provider supports Routes.
The default is configure-cloud-routes=true, and it will only try to
configure routes if allocate-node-cidrs is also configured, so the
default behaviour is unchanged.
This is useful because on AWS the cloud provider configures routes by
setting up VPC routing table entries, but there is a limit of 50
entries. So setting configure-cloud-routes on AWS would allow us to
continue to allocate node CIDRs as today, but replace the VPC
route-table mechanism with something not limited to 50 nodes.
We can't just turn off the cloud-provider entirely because it also
controls other things - node discovery, load balancer creation etc.

Push public key to project if not already present
Fixes https://github.com/kubernetes/kubernetes/issues/26128
Fixes https://github.com/kubernetes/kubernetes/issues/26129
Whenever the ssh key changes (which happens right now whenever we add/change a new jenkins agent) this key will not get pushed to the project until either `gcloud compute ssh` or `gcloud compute config-ssh` runs. As a result instances on this project will reject ssh attempts with this key.
In many cases this will not happen until after a test on a project fails and we attempt to ssh to the nodes to grab logs.
This verifies the presence of the ssh key before starting tests, and attempts to add it if it is missing.

Expose GET and PATCH for status subresource
We can do this for other status subresource. I only updated node/status in this PR to unblock https://github.com/kubernetes/node-problem-detector/issues/9.

The length of an IP can be 4 or 16, and even if 16 it can be a valid
ipv4 address. This check is the more-correct way to handle this, and it
also provides more granular error messages.
Jenkins relies on junit.xml to identify test failures
and non-0 exit codes to indentify infrastructure failures.
Test failures in kubemark tests should not cause the test
script to exit non-0. Infrastructure failures should.
- Add function to dump cluster logs without exiting (refactor)
- Change `test/kubemark/stop-kubemark.sh` to be run regardless of whether tests fail or not
- Exit code for failed tests overwritten to be the exit code of dumping the cluster logs
This replaces the previous creation of mounts from the `volumeGetter`
with mounts provided via RunContainerOptions.
This is motivated by the fact that the latter has a more complete set of
mounts (e.g. the `/etc/hosts` one created in kubelet.go).
