In CentOS 8 and also Fedora the configuration and start of chrony
fails with
Fatal error : adjtimex(0x8001) failed : Operation not permitted

NTP will not be needed before a separate namespace is used for clocks.
Building containers for CentOS and Fedora were failing due to image
download failure. The container build process was fixed by changing
the base images.
Ansible best practice is to not use `latest` for the `package` module
state. As we want to use it in the case of nss, this change will
disable checking for this case.
Added a pipeline file (tests/azure/build-containers.yml) to build test
containers and upload them to quay.io. The pipeline will create
containers with IPA pre-installed for testing proposes on three
different Linux containers: CentOS 7, CentOS 8 and Fedora Latest.
* Adapted tests/test_playbook_runs.py script to allow tests to be
executed from a docker container.
* Added molecule scenarios to create/destroy test containers and
respective documentation in tests/README.md.
