xenapi: ephemeral disk partitions not filling the whole disk

[John Garbutt]

When creating an ephemeral disk, the partition does not quite fill the full disk.

For example:

Model: Xen Virtual Block Device (xvd)
Disk /dev/xvdf: 300GiB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:

Number Start End Size Type File system Flags
 1 0.00GiB 286GiB 286GiB primary

    xenapi: ephemeral disk partition should fill disk

    The current code looks to specify the expected start and finish values
    for the partition. A unit miss match between what nova and parted count
    as a GB seem to cause the difference.

    As we just want to fill the whole disk, we can pass "-0" as the end
    value, to tell parted to extend the partition to the end of the disk.
