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. Change-Id: Ic6a1c69a34241f4fbe617a0b12aec9b1528ba352 Story: 2006574 Task: 38825
