Ansible is complaining about how packages are installed using yum

[emisca]

[DEPRECATION WARNING]: Invoking "yum" only once while using a loop via
squash_actions is deprecated. Instead of using a loop to supply multiple items
and specifying `pkg: "{{ item }}"`, please use `pkg: ['krb5-workstation',
'krb5-devel', 'gcc', 'python-devel']` and remove the loop. This feature will be
 removed in version 2.11. Deprecation warnings can be disabled by setting
deprecation_warnings=False in ansible.cfg.

We need to fix the ansible tasks as suggested..
