Improve Start and Stop DX

[tonysm]

Changed

• Adds the ability to start and stop containers by service name. Currently, to start/stop specific containers we need to pass the container ID. With this change, we get the ability to also pass the service name of such containers. This makes the start/stop commands behave closer to enable/disable.
