Include molecule-hetznercloud plugin in testing

Molecule and Ansible details

N/A

Desired Behavior

I remember having my plugin in molecule upstream testing and then now I see it is gone? I checked https://github.com/ansible-community/molecule/blob/master/tox.ini#L162. I still maintain this plugin. There are users. It would be nice to be informed if the upstream considers that my plugin is not maintained anymore?

Actual Behaviour

My plugin stays in https://github.com/ansible-community/molecule/blob/master/tox.ini#L162 and if it is removed or a decision is made to drop support, I get a ping. There is some process for knowing when I can be included or not. I am pretty responsive to notifications for the plugin.
