docker: cms variable debug becomes /root in docker instead of True

[jpfleischer]

the bug can be replicated by starting a cloudmesh docker, and then try the pytest. then labelmaker yields debug=/root. not debug=True. a fix is to say cms debug on

[laszewsk]

there may be a program called cms in docker that overwrites what our cms is doing?
please can you do which cms and find out if its the cms we use or something else

[laszewsk]

lets just document that in the documentation .... so we need a docker.md or a section somewhere where we explain how to run it in a container.

make image
make ...
