Tonis Tiigi 05cc737f54 Fix container mount cleanup issues
- Refactor generic and path based cleanup functions into a single function.
- Include aufs and zfs mounts in the mounts cleanup.
- Containers that receive exit event on restore don't require manual cleanup.
- Make missing sandbox id message a warning because currently sandboxes are always cleared on startup. libnetwork#975
- Don't unmount volumes for containers that don't have base path. Shouldn't be needed after #21372
