Attempt to make image smaller using docker-slim

[TJM]

This cli tool is on a fairly large docker image. It would be a good thing to make the image smaller. I have been looking at a tool called "docker-slim" which takes the image and only includes the tools needed to run by inspecting the process and what files it uses. I am hoping that maybe you have a "test" script we can run that would put morpheus-cli through its paces, or can at least recommend a list of commands to test everything as per slimtoolkit/slim#101 and https://github.com/docker-slim/examples/tree/master/3rdparty/morpheus-cli

Thanks in advance,
Tommy
