[GCE kube-up] Allow creating/deleting custom network
**What this PR does / why we need it**:
From https://github.com/kubernetes/test-infra/issues/4472.
This is the first step to make PR jobs use custom network instead of auto network (so that we will be less likely hitting subnetwork quota issue).
The last commit is purely for testing out the changes on PR jobs. It will be removed after review.

This allows the etcd docker registry that is currently hard coded to
`gcr.io/google_containers/etcd` in the `etcd.manifest` template to be
overridden. This can be used to test new versions of etcd with
kubernetes that have not yet been published to
`gcr.io/google_containers/etcd` and also enables cluster operators to
manage the etcd images used by their cluster in an internal
repository.

Add launching Cluster Autoscaler in Kubemark
**What this PR does / why we need it**:
Allows to launch Cluster Autoscaler in Kubemark.
To do it, set ENABLE_KUBEMARK_CLUSTER_AUTOSCALER flag to true. This currently only works with one nodegroup, for which you can specify minimum and maximum number of nodes and name. (KUBEMARK_AUTOSCALER_MIN_NODES, KUBEMARK_AUTOSCALER_MAX_NODES, KUBEMARK_AUTOSCALER_MIG_NAME).
Is is important to note that NUM_NODES has a different meaning when launching Cluster Autoscaler - we always start with only one node, but NUM_NODES is used to calculate the size of Kubemark master and addon components.
There are no changes to the current setup if ENABLE_KUBEMARK_CLUSTER_AUTOSCALER is set to false.

Build hyperkube image using Bazel
**What this PR does / why we need it**: Before we had the hyperkube base image, it was difficult to build the hyperkube with Bazel. Now that we have the base image with all the necessary dependencies, this has become trivial.
This will enable federation jobs etc on prow.

Change RBAC storage version to v1 for 1.9
v1 was introduced in 1.8, but storage version remained at v1beta1 to accommodate HA rolling upgrades. in 1.9, we can change the persisted and preferred version to v1

RBAC objects are now stored in etcd in v1 format. After completing an upgrade to 1.9, RBAC objects (Roles, RoleBindings, ClusterRoles, ClusterRoleBindings) should be migrated to ensure all persisted objects are written in `v1` format, prior to `v1alpha1` support being removed in a future release.
