support unpartitioned disks in factory

[dwlehman]

Add support for skipping the partitioning step in DeviceFactory. This would probably involve forcing the container size policy to SIZE_POLICY_MAX.

[GoPerry]

We also have the need to support factory installation when the local disk already have one resource partition .

If we put the intsallation resource in the local disk ,then the blivet will panic..

_ped.IOException: Partition(s) 5 on /dev/md/Volume0_0 have been written, but we have been unable to inform the kernel of the change, probably because it/they are in use. As a result, the old partition(s) will remain in use. You should reboot now before making further changes.
