Since overlayfs is now part of the mainstream kernel, it makes sense to take advantage of it to speed up the container creation process. This patch implements a base container to be used in the container creation process if 'overlayfs' is set as the container backing store. Change-Id: I20123b83af10c0890f4d5945b9fb230acd664213
