O-Subject: [RHEL7.6/7.5.z cloud-init PATCH 2/2] DataSourceAzure.py: use hostnamectl to set hostname
Bugzilla: 1568717

The right way to set hostname in RHEL7 is:

 $ hostnamectl set-hostname HOSTNAME

DataSourceAzure, however, uses:
 $ hostname HOSTSNAME

instead and this causes problems. We can't simply change
'BUILTIN_DS_CONFIG' in DataSourceAzure.py as 'hostname' is being used
for both getting and setting the hostname.

Long term, this should be fixed in a different way. Cloud-init
has distro-specific hostname setting/getting (see
cloudinit/distros/rhel.py) and DataSourceAzure.py needs to be switched
to use these.

Resolves: rhbz#1434109

X-downstream-only: yes
