add HOME env variable for kube-addons service
Fix https://github.com/kubernetes/kubernetes/issues/23973.
Briefly, systemd service does not know the `HOME` environment variable which causes the kubectl write schema file into `/.kube` while it is expected to be `/root/.kube`.

don't ship kube-registry-proxy and pause images in tars.
pause is built into containervm. if it's not on the machine we should just pull
it. nobody that I'm aware of uses kube-registry-proxy and it makes build/deployment
more complicated and slower.

use apply instead of create to setup namespaces and tokens in addon manager
when the addon manager restarts, it takes ~15 minutes (1000 seconds) to start the sync loop because it retries creation of namespace and tokens 100 times. Create fails if the tokens already exist. Just use apply.
This change support running kubernetes master on Ubuntu Trusty.
It uses pure cloud-config and shell scripts, and completely gets
rid of saltstack or the release salt tarball.
The version of Salt we're running doesn't do a good job of detecting
systemd. Inspired by https://github.com/saltstack/salt/issues/13926,
I added a provider-force to the services.
With this change, salt-call -l debug state.highstate succeeds, even for
repeated invocations.
The issue was (probably) benign, but definitely caused noised (e.g. #11297)
To build the python image, BUILD_PYTHON_IMAGE should be set during make.
When the addon script is running, it will check if python is installed
on the machine, if not, it will use the python image that built previously.
This registry can be accessed through proxies that run on each node
listening on port 5000. We send the proxy images to the nodes directly
to avoid requests that hit the network during cluster launch. For now,
we continue to pull the registry itself over the network, especially
given its large size (we should be able to dramatically shrink the
image). On GCE we create a PD and use that for storage, otherwise we
use an emptyDir. The registry is not enabled outside of GCE. All
communication is currently plain HTTP. In order to use SSL, we will
need to be able to request a certificate/key from the apiserver signed
by the apiserver's CA cert.
Instead of hard coding kube-cert and /srv/kubernetes allow these to be
overwritten by environment variables. / is immutable on some systems
and so /srv is not a possible location to store data.
This may help Salt reload services correctly, although we still
need the script until Salt's bug with reloading services on systemd
is resolved.
