Ansible5 fixes

[GMW99]

Epel has now released version 5.4 of Ansible within stable with this there are a few things that broke these are the fixes.

• Selinux commands
  • Ansible no longer defaults to platform-python which is python3.6 which allows the python36-libselinux package to be used, instead it uses python3.8 and therefore the libselinux package cannot be used due to being a different version. The fix was to set the ansible python interpreter to platform-python as this defaults to python3.6 and is the recommended solution: https://bugzilla.redhat.com/show_bug.cgi?id=2091684
• grafana_datasource module
  • The fix was to change url to ds_url as due to this version update url no longer aliases to ds_url and now is an alias to grafana_url, therefore making the url explicit with ds_url fixed this problem. An overview of the new format can be found here: https://docs.ansible.com/ansible/5/collections/community/grafana/grafana_datasource_module.html.
