Running on Fed 32 machine with Docker Daemon running requires some workarounds

[astoycos]

When trying to deploy a cluster on my Fedora 32 Host, where I reverted to CgroupsV1 to run the docker daemon, I had to follow some steps to get the playbook running properly when following the instructions suggested here

1. Ensure sshd is active with systemctl status sshd if it is not, activate with systemctl start sshd
2. Disable firewalld since it conflicts with docker on some IPtable rules. Simply run systemctl stop firewall
3. Make sure libvirts default virtual network is created with virsh net-list, it should be by default. If it is not create it with virsh net-start default
