Re-add kube_proxy to the abac file (Match what we had in 1.5).
**What this PR does / why we need it**:
Make the ABAC file match what it was in 1.5. GKE rewrites the ABAC file every time, so we were clobbering the kube_proxy entry that used to exist. This would have gone unnoticed, but a separate bug in GKE is causing the token file rewrites to fail on GKE (meaning group used in RBAC aren't there).

Add ability to enable cache mutation detector in GCE
Add the ability to enable the cache mutation detector in GCE. The current default behavior (disabled) is retained.
When paired with https://github.com/kubernetes/test-infra/pull/1901, we'll be able to detect shared informer cache mutations in gce e2e PR jobs.
Allow cache mutation detector enablement by PRs in an attempt to find
mutations before they're merged in to the code base. It's just for the
apiserver and controller-manager for now. If/when the other components
start using a SharedInformerFactory, we should set them up just like
this as well.
For now, this is focused on a fixed set of flags that makes the audit
log show up under /var/log/kube-apiserver-audit.log and behave similarly
to /var/log/kube-apiserver.log. Allowing other customization would
require significantly more complex changes.
Audit log rotation is handled externally by the wildcard /var/log/*.log
already configured in configure-helper.sh.
/etc/ssl/certs is currently mounted through in a number of places.
However, on Gentoo and CoreOS (and probably others), the files in
/etc/ssl/certs are just symlinks to files in /usr/share/ca-certificates.
For these components to correclty work, the target of the symlinks needs
to be available as well.
This is especially important for kube-controller-manager, where this
issue was noticed.
This change was originally part of #33965, but was split out for ease of
review.

Enable setting up Kubernetes cluster in Ubuntu on Azure
Implement basic cloud provider functionality to deploy Kubernetes on
Azure. SaltStack is used to deploy Kubernetes on top of Ubuntu
virtual machines. OpenVpn provides network connectivity. For
kubelet authentication, we use basic authentication (username and
password). The scripts use the legacy Azure Service Management APIs.
We have set up a nightly test job in our Jenkins server for federated
testing to run the e2e test suite on Azure. With the cloud provider
scripts in this commit, 14 e2e test cases pass in this environment.
We plan to implement additional Azure functionality to support more
test cases.

mount instanceid file from config drive when using openstack cloud provider
fix https://github.com/kubernetes/kubernetes/issues/23191, the instanceid file is read however we do not mount it as a volume, and it would cause the cloud provider contacts the metadata server, in some cases, the metadata server is not able to serve, then the cloud provider would fail to initialize, we should avoid that.

- 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
CentOS 7 Core nodes running on OpenStack with an SSL-enabled API
endpoint results in the following error without this patch:
F0425 19:00:58.124520 5 server.go:100] Cloud provider could not be initialized: could not init cloud provider "openstack": Post https://my.openstack.cloud:5000/v2.0/tokens: x509: failed to load system roots and no roots provided
The root cause is that the ca-bundle.crt file is actually a symlink
which points to a directory which wasn't previously exposed.

Making the assumption that the person running kube-up has their
Openstack environment setup, those same variables are being passed
into heat, and then into openstack.conf.
The salt codebase was modified to add openstack as well.

Initial kube-up support for VMware's Photon Controller
This is for: https://github.com/kubernetes/kubernetes/issues/24121
Photon Controller is an open-source cloud management platform. More
information is available at:
http://vmware.github.io/photon-controller/
This commit provides initial support for Photon Controller. The
following features are tested and working:
- kube-up and kube-down
- Basic pod and service management
- Networking within the Kubernetes cluster
- UI and DNS addons
It has been tested with a Kubernetes cluster of up to 10
nodes. Further work on scaling is planned for the near future.
Internally we have implemented continuous integration testing and will
run it multiple times per day against the Kubernetes master branch
once this is integrated so we can quickly react to problems.
A few things have not yet been implemented, but are planned:
- Support for kube-push
- Support for test-build-release, test-setup, test-teardown
Assuming this is accepted for inclusion, we will write documentation
for the kubernetes.io site.
We have included a script to help users configure Photon Controller
for use with Kubernetes. While not required, it will help some
users get started more quickly. It will be documented.
We are aware of the kube-deploy efforts and will track them and
support them as appropriate.

This change revises the way to provide kube-system manifests for clusters on Trusty. Originally, we maintained copies of some manifests under cluster/gce/trusty/kube-manifests, which is not scalable and hard to maintain. With this change, clusters on Trusty will use the same source of manifests as ContainerVM. This change also fixes some minor problems such as shell variables and comments to meet the style guidance better.
