Description of problem:

XFS has label length limit of 12 characters while diskimage-builder uses a hardcoded label "cloudimg-rootfs" which is 15 characters long. It is impossible to build image with XFS filesystem as the diskimage-builder uses hardcoded filesystem label "cloudimg-rootfs" which exceeds the label length limit of 12 characters of XFS.

Version-Release number of selected component (if applicable):

diskimage-builder-0.1.5-4.el7ost.noarch.rpm

How reproducible:
always

Steps to Reproduce:
1. build image with XFS filesystem with diskimage-builder
2.
3.

Actual results:
For root filesystem disk image builder uses LABEL cloudimg-rootfs. Eg, in /etc/fstab. With xfs filesystem we can use only a 12 character LABEL. Hence disk image builder does not work with xfs. 

Expected results:
