I can't tell you in detail, but the 'kolla_action' is what you specify
i.e. reconfigure, deploy, upgrade, and that translates to a playbook,
called from tasks/main.yml. Each role has tasks/upgrade.yml
tasks/deploy.yml etc which you can inspect for the differences. In my
case this is in /usr/local/share/kolla-ansible/ansible/roles/

Also, running kolla-ansible by itself gives you a brief description:
     deploy               Deploy and start all kolla containers
     reconfigure          Reconfigure OpenStack service
     upgrade              Upgrades existing OpenStack Environment

Also you can look at links like
https://docs.openstack.org/project-deploy-guide/kolla-ansible/latest/quickstart.html#deployment
https://docs.openstack.org/kolla-ansible/latest/user/operating-kolla.html
