Adds GCEPersistentDisk volume struct
Adds gce-utils to attach disk to kubelet's VM.
Updates config to give compute-rw to every minion.
Adds GCEPersistentDisk to API
Adds ability to mount attached disks
Generalizes PD and adds tests.
PD now uses an pluggable API interface.
Unit Tests more cleanly separates TearDown and SetUp
Modify boilerplate hook to omit build tags
Adds Mounter interface; mount is now built by OS
TearDown() for PD now detaches disk on final refcount
Un-generalized PD; GCE calls moved to cloudprovider
Address comments.
Cloud providers may need specific configurations to run properly (e.g.
authentication parameters, uri, etc.).
This patch adds the simplest implementation for passing configurations
to cloudproviders: a new apiserver -cloud_config flag to specify the
path to an arbitrary configuration file.
