This fix contains few things:
* Used k8s.gcr.io/debian-base-amd64:v2.0.0 as base image to build storage-provisioner
* Modify RBAC permission used to cluster-admin
* Build storage-provisioner as static binary
Some users (especially for those in mainland China) may have issue
accessing the default image repository. This patchset allows users
to override the default image repository gcr.io to a different
repository by specifying --image-repository option in the command
line as a simple workaround. Images will be pulled from the
specified image repository instead of the default ones.
Example (using mirror by Aliyun):
minikube start ...
--image-repository
registry.cn-hangzhou.aliyuncs.com/google_containers
