Title:
  CloudStack datasource fails to find DHCP lease if IPv6 present

Status in cloud-init:
  Fix Committed
Status in cloud-init package in Ubuntu:
  Fix Released

Bug description:
  The CloudStack data source looks in /var/lib/dhcp for DHCP lease files
  and compares the timestamps.

  If you have a dhclient.leases and dhclient6.leases file present it
  will look in the dhclient6.leases file for a DHCP server to connect
  to.

  The fix for this is rather simple, change a if-statement so that it
  checks if the leases file starts with 'dhclient.'

          if file_name.startswith("dhclient.") and \
             (file_name.endswith(".lease") or file_name.endswith(".leases")):
