Boot from volume doesn't honour the minDisk parameter

Bug Description

The Glance image system includes minDisk and minRam specifications to guide the Nova code in terms of the minimum disk and memory requirements for the instance.

The cinder create_volume from image doesn't look at the metadata so it is possible that the specified volume size is actually too small for the image. As images are often stored as QCOW files, the actual image size itself isn't representative of the disk size needed for the image.

    Check that volume is at least minDisk size.

    The Image service (such as Glance) provides a minDisk parameter to
    indicate the minimum required disk size for the image. This change
    ensures that the guidance is followed in the case of bootable
    volumes.

    Added unit test and fixed PEP8 issue.

    Fixed issue with docstring.

    Added a comment.

    Fixes Bug #1175532
