With ansible 2.3.1 it is possible to have one place as an additional utils module to do all the needed steps to be able to generate the environment for new and older ipa versions. The library modules are now a lot smaller. The minimal ansible version has been increased to 2.3.1. In the future it might now also be possible to have a special ansible_ipa_client version for ipa < 4.4 in this utils module.
