Mark Goddard a91135179d CentOS 8: Use ansible_playbook_python for localhost dependencies
Currently we install python dependencies on the Ansible control host
each time the ip-allocation and console-allocation roles are executed.
This is inefficient, particularly in the case of the ip-allocation role
which is run serially for all hosts. It is also unnecessary since we
have these packages available in the Python environment used to execute
kayobe.

The kolla-ansible role also has an implicit dependency on PyYAML for
managing kolla passwords.

This change uses ansible_playbook_python as the Python interpreter for
the necessary tasks in these roles to avoid installing dependencies on
the system on CentOS 8 and Ubuntu. For CentOS 7 we still need to use the
platform Python, due to needing SELinux bindings.
