Error running docker-storage-setup in multipath enviroment

Issue

When trying to setup docker storage in a "multipath" environment, if we are using the container-storage-setup 0.9.0-1 version or lower, we will get this error:

# docker-storage-setup
ERROR: Device /dev/sdX is already partitioned and cannot be added to volume group VG_docker

The issue is that seems that docker-storage-setup can't create the LVs whit multipath.
The /usr/bin/container-storage-setup script checks to see if the specified device has a parent to ensure that the device is not a loop device. Multipath (mpath) devices also have a parent, so the script incorrectly believes that the mpath device is a loop device.
