Openstack-ansible aio fails on centos8 for deprecated support of python

[Kalpit]

I'm trying to install OpenStack using OpenStack-ansible (AIO) all in one installation on centos 8. The issue I'm facing is that python is no longer supported in centos 8, instead, python2 and python3 are recommended. I'm asking for help and reporting a bug that Is there any way so that I can install OpenStack using OpenStack aio on centos 8. Please help me out! Thanks in advance fellow members.

python2-dnf is not being installed in centos 8 and I'm stuck at that point.

Error appearing on the console:

fatal: [localhost]: FAILED! => {"changed": false, "cmd": "dnf install -y python2-dnf", "msg": "Could not import the dnf python module using /usr/bin/python (2.7.15 (default, Oct 8 2019, 21:08:29) [GCC 8.2.1 20180905 (Red Hat 8.2.1-3)]).

Unfortunatelly we don't support centos 8 at this point. You can see supported operating system on this page https://docs.openstack.org/project-deploy-guide/openstack-ansible/latest/targethosts-prepare.html#installing-the-operating-system

We have plans to implement centos 8 support for Ussuri.
