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.
This is for internal use at the moment, for testing Ubernetes Lite, but
arguably makes the code a little cleaner.
Also rename KUBE_SHARE_MASTER -> KUBE_USE_EXISTING_MASTER
Some functionality in hack/lib is currently depended on by
cluster/common.sh so kube-up from the full release tar (which
does not include hack/) is currently broken. With this PR we
create cluster/lib/ and move the necessary bits from hack/
over to get kube-up working again.

This change refactors the code of preparing kube-system manifests
for trusty based cluster. The manifests used by nodes do not contain
salt configuration, so we can simply copy them from the directory
cluster/saltbase/salt, make a tarball, and upload to Google Storage.
The node.yaml has some logic that will be also used by the kubernetes
master on trusty work (issue #16702). This change moves the code
shared by the master and node configuration to a separate script, and
the master and node configuration can source it to use the code.
Moreover, this change stages the script for GKE use.
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.

Allows loading existing auth from kubeconfig on kube-up if a
valid KUBE_CONTEXT is specified, instead of always force
regenerating auth (basic or token) when creating a new cluster.
- Refactor common and gce/upgrade.sh to use arbitrary published releases
- Update hack/get-build to use cluster/common code
- Use hack/get-build.sh in cluster upgrade test logic
