Fix multiple CI failures

1. Blacklist Ansible 2.9.8

Ansible 2.9.8 includes a regression on the fileglob plugin [1] that
causes the Kolla Ansible HAProxy role to fail.

This change blacklists Ansible 2.9.8 to work around the issue.

2. Use ensure-docker role instead of install-docker

The install-* roles are being deprecated and renamed to follow the
ensure-* naming convention [2].
