The way docker works is if a user specifies a non `-e Name=Value`, IE
just a `-e Name`, then the environment variable Name from the clients
OS.ENV is used.
Also by default Docker containers run with the HOSTNAME environment set
to the HOSTNAME specified for the container.

Create unittests for the create_cli helper functions. As
such, remove cli context usage from the functions to
further divide between cli input and parsing. Also, simplifies
unit testing.
