[CI] Remove ansible-test custom containers (#650)

* Cut tests containers

* Cut unused flatten versions

* Fix installation of mysqlclient on Ubuntu

* Cut unused variables

* Fix package missing on Unbuntu 22.04

* Fix variable templating

* Fix test for ansible 2.17 and do remove the ignore_errors

ignore_errors is bad because it makes searching for real errors
difficult.
