vmdisks.py also had some functions to manipulate the guest disk XML. So move them to xmlutils/disk.py Also update the references to it on Kimchi code.

When generating the disk XML, the most common information to generate the device name are: 1) the bus - to identify the right prefix, and 2) the disk index. Add this logic to get_disk_xml() so when no 'dev' name is specified the device name will be automatically generated according to bus and index value.
