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).
Teardown can run before Setup when the kubelet is restarted... in that
case, the shaper was nil and thus calling the shaper resulted in a panic
This fixes that by ensuring the shaper is always set... +1 level of
indirection and all that.
Before this change, the podCIDRs map contained both cidrs and ips
depending on which code path entered a container into it.
Specifically, SetUpPod would enter a CIDR while GetPodNetworkStatus
would enter an IP.
This normalizes both of them to always enter just IP addresses.
This also removes the now-redundant cidr parsing that was used to get
the ip before
