A docker containter with the docker
client installed to be able to run docker command.
The most common usecase is when you have a Cloud VM that you don't have access to or don't
to install/run processes directly on the VM, you can still run this container and run docker
commands from it (e.g. start, restart or kill another container on the host VM).
