* Add a pillar for hostname (because even if there's a good Salt
function for it, I don't trust it to return the short hostname)
* Move INITIAL_ETCD_CLUSTER to just the GCE turn-up
* Remove the master_name, which isn't needed as a pillar
Particularly on smaller instances on AWS, we were hitting the 80 second
timeout now that our image is well over the 1GB mark.
Increase the timeout from 80 seconds to 300 seconds.

Substitute federation_domain_map parameter with its value in node bootstrap scripts.
This PR also removes the substitution code we added to the build scripts.
**Release Note**
```release-note
If you use one of the kube-dns replication controller manifest in `cluster/saltbase/salt/kube-dns`, i.e. `cluster/saltbase/salt/kube-dns/{skydns-rc.yaml.base,skydns-rc.yaml.in}`, either substitute one of `__PILLAR__FEDERATIONS__DOMAIN__MAP__` or `{{ pillar['federations_domain_map'] }}` with the corresponding federation name to domain name value or remove them if you do not support cluster federation at this time. If you plan to substitute the parameter with its value, here is an example for `{{ pillar['federations_domain_map'] }`
pillar['federations_domain_map'] = "- --federations=myfederation=federation.test"
where `myfederation` is the name of the federation and `federation.test` is the domain name registered for the federation.

Add Calico as policy provider in GCE
Adds Calico as policy provider to GCE, enforcing the extensions/v1beta1 NetworkPolicy API.
Still to do:
- [x] Enable NetworkPolicy API when POLICY_PROVIDER is provided.
- [x] Fix CNI plugin, policy controller versions.
CC @thockin - does this general approach look good?

Filters can't exceed 4k, and GET requests against the GCE API are also
limited, so these break down in different ways at different cluster
counts. Fix it by introducing an advisory node-instance-prefix
configuration in the GCE provider that can hint the
EnsureLoadBalancer/UpdateLoadBalancer code (and the firewall
creation/update code). If it's not there, or wrong (a hostname that's
registered violates it), just ignore it and grab the whole project.
This change adds support for mounting local ssds on GCI.
It updates the previous container-vm behavior as well to
match that for GCI nodes by mounting the local-ssds under
the same path (/mnt/disks/ssdN).

Add node problem detector as an addon pod.
```release-note
Introduce a new add-on pod NodeProblemDetector.
NodeProblemDetector is a DaemonSet running on each node, monitoring node health and reporting
node problems as NodeCondition and Event. Currently it already supports kernel log monitoring, and
will support more problem detection in the future. It is enabled by default on gce now.
```
This PR enables NodeProblemDetector as an add-on pod.

Configuration for GCP webhook authentication and authorization
This PR adds configuration for GCP webhook authentication and authorization in ContainerVM and GCI. The change of configure-vm.sh and kube-apiserver.manifest is directly copied from @cjcullen's PR #25380 and #25296. The change in GCI script configure-helper.sh includes the support for webhook authentication and authorization, and also some code refactor to improve readability.
@cjcullen @roberthbailey @zmerlynn please review it. The original PRs are P1, please mark this as P1.
cc/ @fabioy @kubernetes/goog-image FYI.
I verified it by running e2e tests on GCI cluster. Without the GCI side change, cluster creation fails as being capture by GKE Jenkins tests. I don't test when the two env GCP_AUTHN_URL and GCP_AUTHZ_URL are set, because they are only set in GKE. After this PR is merged, @cjcullen will test in GKE.

Salt configuration for the new Cluster Autoscaler for GCE
Adds support for cloud autoscaler from contrib/cloud-autoscaler in kube-up.sh GCE script.
cc: @fgrzadkowski @piosz
This only applies to gce kube-up. 60 seconds of open connection should
be sufficient for anything that we should be downloading. The release
tar is currently 255M.
This should allow allow the non_masquerade_cidr option to get configured
in /etc/salt/minion.d/grains.conf, allowing the flag to used by kubelet
in /etc/sysconfig/kubelet. Default configuration is set in pillar
* In kube-up.sh, create a staging bucket with a location nearest the
zone being created. If new variable RELEASE_REGION_FALLBACK is set
(default false), create multiple buckets and stage to fallback
URLs. (In open source, this path is primarily for testing.)
* In configure-vm.sh, split the URL env variables by comma (if any
extra are present) and retry on the fallback URLs. Also factor the
hash checking into this path rather than outside, since a corrupt
release in a particular geo can be retried in a different geo.
* Remove the local already-staged .tar.gz checks. They've caused
several issues along the way, and with this code path become virtually
unmaintainable. (I could add a sentinel for each bucket it's possibly
staged to, but ew.)
We run unattened-upgrades manually, and then reboot automatically if we
find /var/run/reboot-required; then we check if any services need
restarting and restart them automatically using the needrestart tool.
This should mean we don't _have_ to build new images on every security
update, though we can do so to avoid a reboot.
Issue #21382
We adapt the existing code to work across all zones in a region.
We require a feature-flag to enable Ubernetes-Lite
Reasons:
* There are some behavioural changes if users create volumes with
the same name in two zones.
* We don't want to make one API call per zone if we're not running
Ubernetes-Lite.
* Ubernetes-Lite is still experimental.
There isn't a parallel flag implemented for AWS, because at the moment
there would be no behaviour changes from this.
Addresses #15968
This patch removes KUBE_ENABLE_EXPERIMENTAL_API and similar calls in
favor of specifying desired features in KUBE_RUNTIME_CONFIG. Changes
have also been made to e2e scripts to re-enable using
KUBE_RUNTIME_CONFIG rather than EXPERIMENTAL_API env vars.
This also introduces KUBE_ENABLE_DAEMONSETS and KUBE_ENABLE_DEPLOYMENTS.

If the `hostname` commands used in the polling loop fail, their stdout
is going to be empty and so `getent hosts` command will actually
succeed. For the loop to work as expected, make sure the subcommands
return a string which is an invalid host name.
