Title:
  hostname is set incorrectly if localhostname is fully qualified

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

Bug description:
  If no data source is available and the local hostname is set to
  "localhost.localdomain", and /etc/hosts looks like:

    127.0.0.1   localhost localhost.localdomain localhost4
  localhost4.localdomain4

  Then in sources/__init__.py in get_hostname:

  - util.get_hostname() will return 'localhost.localdomain'
  - util.get_fqdn_from_hosts(hostname) will return 'localhost'
  - 'toks' will be set to [ 'localhost.localdomain', 'localdomain'

  And ultimately the system hostname will be set to
  'localhost.localdomain.localdomain', which isn't useful to anybody.
