Title:
  redhat is different from sles when setting hostname by cloud-init.

Status in cloud-init:
  Expired

Bug description:
  Boot a vm with redhat image via openstack, after vm start up, type
  hostname command ,find it set the hostname with string .novalocal,
  this is not expect.

  Steps of reproduce.
  1 Boot two vms, one is rhel, one is suse for comparision, set the vms name with ".test" for both
  nova boot --flavor 0g0 --image rhel72image rhel72.test
  nova boot --flavor 0g0 --image sles12image sles12hostname.test

  2 The boot success.
  nova list
  | dcbd39cb-4cfc-4298-942e-44232a157551 | rhel72.test            | ACTIVE        | -          | Running     | mgt_network503=192.168.99.7  |
  | 662e00e1-ca27-4e8a-b490-80a3296bbe29 | sles12hostname.test    | ACTIVE        | -          | Running     | mgt_network503=192.168.99.16 |

  3 Logon the vm, and type hostname command.
  Logon rhel vm:
  [root@rhel72 ~]# hostname
  rhel72.test.novalocal

  sles12hostname:~ # hostname
  sles12hostname

  4 I don't change the default logger for cloud-init on both vms. We
  don't expect rhel is set with hostname "rhel72.test.novalocal" (It's
  from configdrive's meta_data.json I think). What I expect is rhel can
  behavior similar as sles do,just set rhel72 as its hostname.

  Here are the meta_data.json for both
