Python deprecation warning when running Ansible playbook on Red Hat Enterprise Linux 8

Issue

• When running ansible-playbook or ansible ad-hoc commands on a Red Hat Enterprise Linux 8 you may show a python deprecation warning message.

  The following warning message will be exhibited when /usr/bin/python is present on the host.

  [DEPRECATION WARNING]: Distribution redhat 8.x on host xxx.xxx.xxx.xxx should use /usr/libexec/platform-python, but is using /usr/bin/python for backward compatibility with prior Ansible releases. A future Ansible release will default to using the discovered platform python for this host. See https://docs.ansible.com/ansible/2.9/reference_appendices/interpreter_discovery.html for more information. This feature will be removed in version 2.12. Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.
