feat: Add RHEL9 support

[smolin-de]

Add RHEL9 kickstart for bastion host (#160).
Support for openvpn must be removed in an additional PR, because the robertdebock.openvpn packages can not be installed on RHEL9.

Will this also work if user has rhel 8 bastion?.

ok just checking. It might be good to validate this. We dont know how quickly people will shift to rhel 9 bastion.

But, we know that there will be issues. e.g. openvpn can not be installed on rhel9, some package name changed, the default python3 version will change from 3.6 to 3.9, ...

Might be good to keep both ks files then and pick based on rhel type?
