Cleanups to use pillar.get instead of pillar for safety plus the
ability to specify extra options on ntpd.
Fixing duplicate /etc/sysconfig/init block.
Corrected /etc/cron.allow to be a file rather than a directory and
to have a default of root and no other users.
Users should be added to a pillar variable as below:
cron_users: |
  user1
  user2
Corrected SELinux printout for selinux_state pillar variable.
