Dan Walsh 6d04587343 Remount /var/lib/docker as --private to fix scaling issue ...

If an admin mounts all file systems as -rshared (Default on RHEL and Fedora)
we see a scaling problem as the number of container increase.

Basically every new container needs to have it new mounts in /var/lib/docker
shared to all other containers, this ends up with us only able to scale to
around 100 containers, before the system slows down.

By simply bind mounting /var/lib/docker on its and then setting it private,
the scaling issue goes away.
