Users are able to pass the disk format (qcow, raw, etc) in disk Template information. However, Kimchi was ignoring this information and always creating QCOW2 disk images (if the storagepool is not 'LOGICAL') when it creates a VM based on a given Template. This patch fixes this problem and also moves the checking and disk format auto assignment to Template creation phase, in VMTemplate class init.
