playbooks,inventory: added playbook installing basic tools on a VM

As soon as a virtual machine is ready, we install docker as it gives
the most flexbility for our CI and the docker images are versionized.
Hence, we install docker as main installation package.
We assume that the VM holds the following users:
- root
- superuser (added to sudoers)
- user
