This is to base the name on the volume not just on the
source configMap. If you have 2 volumes that both have the same
configMap as a source, the volume is see as being in the attached
state (it's state is looked up based on GetVolumeName()).
See bug #28502
Fake clientset no longer needs to be prepopulated with records: keeping
them in leads to the name conflict on creates. Also, since fake
clientset now respects namespaces, we need to correctly populate them.
This commit adds a new volume manager in kubelet that synchronizes
volume mount/unmount (and attach/detach, if attach/detach controller
is not enabled).
This eliminates the race conditions between the pod creation loop
and the orphaned volumes loops. It also removes the unmount/detach
from the `syncPod()` path so volume clean up never blocks the
`syncPod` loop.
