Subject: [PATCH] Allow downgrades in docker_install

When running the installer again on a new node, it tries to pull the docker packages but since the installer ran again before, the install command fails on Ubuntu 18.04 stating that the `--allow-downgrades` is not specified in the command. This change adds that to circumvent the issue.
