* ci: add integration containers for duo and haproxy
This change utilises specific integration containers for the DuoPush and HAProxy suites.
In the case of DuoPush suite specifically in dev mode the container will be built on suite startup.
* ci: factorize pre-command hook and unset async on trigger steps
This change implements yamllint and adjusts all yaml files to abide by our linting setup. This excludes config.template.yml as this will be done in an alternate commit.
