Bump the ansible to 2

[OpenStack Infra]

Dear bug triager. This bug was created since a commit was marked with DOCIMPACT.
Your project "openstack/kolla" is set up so that we directly report the documentation bugs against it. If this needs changing, the docimpact-group option needs to be added for the project. You can ask the OpenStack infra team (#openstack-infra on freenode) for help if you need to.

Change abandoned by Christian Berendt (<email address hidden>) on branch: master
Review: https://review.openstack.org/321525
Reason: There is a new incoming patch (https://review.openstack.org/#/c/329015/), I will abandon this one, this way I do not have to rebase it.
