Generate glance image with SCSI bus type for ppc arch
Generate glance image with SCSI bus type for ppc arch

This patch fixes wrong assumptions for bus types of disk and cdrom
on ppc64. Qemu driver assumes IDE bus type for cdrom device, which
is not supported on ppc arch.
Adds capability to add --property key-value to the glance
image-create command.
Using double brackets for portability reasons.
