Remove init-containers in LVM mode

As we are using 'shared/Bidirectional' mounts for LVM driver also, we could create the needed physical devices(namespaces, volume groups) in the same driver session. This invalidates the usage of init-containers. Few advantages of merging the init-containers functionality to driver code: - smaller container image size - allows us to implement features that are common to both modes(ex: pmemPercentage) FIXES #532
