Hotfix: Ansible install, python2 depricated

As of 23rd January, 2021, pip v21.0 depricated python2
and removed support for python2. As of now, ansible seems to use
python2 for deployment.
pypa/pip#6148

This broke the installation. For hotfix, added customa pip install
command based on Vagrant's ansible local documentation
https://www.vagrantup.com/docs/provisioning/ansible_local

Note: Requires fairly recent version of vagrant
