Brian Goff 6a8ef9223f Make propagated mount persist outside rootfs ...

This persists the "propagated mount" for plugins outside the main
rootfs. This enables `docker plugin upgrade` to not remove potentially
important data during upgrade rather than forcing plugin authors to hard
code a host path to persist data to.

Also migrates old plugins that have a propagated mount which is in the
rootfs on daemon startup.
