Downstream generators that want to reuse the upstream generated types
need to be able to define a different ignore tag (so that they can see
the already generated types).
The staging images are now created with image families, so we can get rid of the
image indices stored in GCS. Also, get images based on milestone number instead
of "image type".

Revert "Revert "GCI: add support for network plugin""
PR #27027 added the network plugin support in GCI config, but later a bug in the network plugin broke e2e tests (see issue #27118). The bug was fixed by #27141 and we have been repeatedly run the serial e2e tests more than 10 times to verify the fix. Now it should be safe to put the GCI network plugin support back.
We will first merge in the master branch and monitor the Jenkins serial tests for a while and then cherry-pick it into release-1.3 branch.

Fixes and improvements to Photon Controller backend for kube-up
- Improve reliability of network address detection by using MAC
address. VMware has a MAC OUI that reliably distinguishes the VM's
NICs from the other NICs (like the CBR). This doesn't rely on the
unreliable reporting of the portgroup.
- Persist route changes. We configure routes on the master and nodes,
but previously we didn't persist them so they didn't last across
reboots. This persists them in /etc/network/interfaces
- Fix regression that didn't configure auth for kube-apiserver with
Photon Controller.
- Reliably run apt-get update: Not doing this can cause apt to fail.
- Remove unused nginx config in salt

Add a custom main instead of the standard test main, to reduce stack …
Adds a custom test main handler (see: `TestMain` in https://golang.org/pkg/testing/ for details)
Partial fix for https://github.com/kubernetes/kubernetes/issues/25965
This does the standard timeout, but strips non-kubernetes stacks out of the stack trace (e.g. it filters things like:

GCI: add support for network plugin
I had run e2e against a cluster with both master and nodes on GCI a couple of times. The PR auto tests will cover the hybrid cluster with just master on GCI.
cc/ @roberthbailey @fabioy @kubernetes/goog-image
Also includes other improvements:
- Makefile rule to run tests against remote instance using existing host or image
- Makefile will reuse an instance created from an image if it was not torn down
- Runner starts gce instances in parallel with building source
- Runner uses instance ip instead of hostname so that it doesn't need to resolve
- Runner supports cleaning up files and processes on an instance without stopping / deleting it
- Runner runs tests using `ginkgo` binary to support running tests in parallel
This PR contains Kubelet changes to enable attach/detach controller control.
* It introduces a new "enable-controller-attach-detach" kubelet flag to
enable control by controller. Default enabled.
* It removes all references "SafeToDetach" annoation from controller.
* It adds the new VolumesInUse field to the Node Status API object.
* It modifies the controller to use VolumesInUse instead of SafeToDetach
annotation to gate detachment.
* There is a bug in node-problem-detector that causes VolumesInUse to
get reset every 30 seconds. Issue https://github.com/kubernetes/node-problem-detector/issues/9
opened to fix that.
This change recovers some of the side effects of
https://github.com/kubernetes/kubernetes/pull/26197, i.e., keeps the defaults of
`NODE_IMAGE` and `NODE_IMAGE_PROJECT` to `MASTER_IMAGE` and
`MASTER_IMAGE_PROJECT`, for backward compatibility. Although it keeps
`OS_DISTRIBUTION` defaulting to `gci`, the default settings of these vars are
moved to `cluster/gce/util.sh` and conditioned on `OS_DISTRIBUTION==gci`.

Support per-test-environment ginkgo flags for node e2e tests to facilitate skipping miss behaving tests in PR builder
We had an issue today where some node e2e tests were timing out in the pr builder. We want to be able to skip tests in the pr builder and leave them running in the CI if this happens again.

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.

Attach Detach Controller Business Logic
This PR adds the meat of the attach/detach controller proposed in #20262.
The PR splits the in-memory cache into a desired and actual state of the world.
