Fix chrony deploy iteritems() issue

[SuperQ]

We ran into an issue with iteritems() in the chrony deploy.

@yoe: Can you paste the error message you got?

[SuperQ]

@paulfantom suspects that this is a Python 2/3 issue and we need to replace iteritems() with items().

My ansible:

$ ansible --version
ansible 2.7.6
  config file = /home/ben/src/FOSDEM/infrastructure/ansible/ansible.cfg
  configured module search path = [u'/home/ben/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/dist-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.15rc1 (default, Nov 12 2018, 14:31:15) [GCC 7.3.0]

wouter@gangtai:~$ ansible --version ansible 2.7.6 config file = /etc/ansible/ansible.cfg configured module search path = ['/home/wouter/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules'] ansible python module location = /usr/lib/python3/dist-packages/ansible executable location = /usr/bin/ansible python version = 3.7.2+ (default, Feb 2 2019, 14:31:48) [GCC 8.2.0] That could be the reason, indeed.
