Conflicts between docker-ce and docker-ce-cli

[deimantastumas]

Describe the Bug

When the older version of docker (anything other than latest) is attempted to be installed, Puppet fails to install the packages.

Expected Behavior

Docker should be properly installed

Steps to Reproduce

1. Try to install the docker 19.03.9-3.el7 version using puppetlabs-docker module
2. Run the puppet

Environment

• Module version: 6.0.2
• Platform: CentOS Linux 7
• Puppet agent/server versions: 6.x

Additional Context

Looks like the latest version of docker-ce-cli is installed as a dependency when installing docker-ce. So if we're using the module to install the Docker 19.03.9-3.el7, it firstly installs the docker-ce version 19.03.9-3.el7, then the latest current version of docker-ce-cli is installed as a dependency (currently 23.0.0-1.el7), then the module tries to install the matching version of docker-ce-cli - 19.03.9-3.el7 and it fails with the following error:

Error: Could not update: Failed to update to version 19.03.9-3.el7, got version 3:23.0.0-1.el7 instead
Error: /Stage[main]/Docker::Install/Package[docker]/ensure: change from 'purged' to '19.03.9-3.el7' failed: Could not update: Failed to update to version 19.03.9-3.el7, got version 3:23.0.0-1.el7 instead (corrective)
