Make the PVC protection controller robust to cases where a Pod X is deleted,
then a Pod Y with the same namespaced name is created and the two events are
delivered via a single update notification. Both pods should be processed,
because X might be blocking deletion of a PVC which is not referenced by Y.
Prior to this commit only the newer pod is processed, which means that it
is possible to leak PVCs.
Also, add unit tests to reflect the change.
default behavior does not change, it uses k8s.gcr.io by default
added two vars: KUBE_DOCKER_REGISTRY, KUBE_BASE_IMAGE_REGISTRY.
KUBE_BASE_IMAGE_REGISTRY is for base image registry of server binaries
KUBE_DOCKER_REGISTRY is for released images registry
user can interact with them by:
`KUBE_DOCKER_REGISTRY=### KUBE_BASE_IMAGE_REGISTRY=### make quick-release`

- Portworx storage plugin under pkg/volume/portworx uses the libopenstorage/openstorage dependency.
- This change does not update any of the go files vendor'ed from libopenstorage/openstorage but simply
updates the go modules vendor from a SHA to the v1.0.0 tag.
The PodInfo tests can be extended to also cover the new
csi.storage.k8s.io/ephemeral flag. However, the presence of that flag
depends on whether inline volume support is enabled, so tests that run
with and without the feature have to detect that at runtime.
Other tests have a feature tag and thus can assume that they only run
when that feature is enabled. However, we need a newer csi-mock driver
before we can actually ask it to publish an ephemeral inline volume.
The conceptual change is that the mode in which a volume gets handled
is derived from it's spec, not from the ability of the driver. In
practice, that is already how the code worked because it didn't
actually look at CSIDriver.Spec.Mode at all.
Therefore the code change itself is mostly just renaming "driver mode"
to "volume mode". In some places (CanDeviceMount, CanAttach) the
feature check that was used elsewhere seemed to be missing. Now their
code path for ephemeral volumes are also only entered if that feature
is enabled.
The sanity check whether a CSI driver is being used correctly still
needs to be implemented.
