Resolving shell environment variables name space conflicts with parm

[TerrenceMcGuinness-NOAA]

Description

This PR updates the instantiation of the Configuration Class of wxflow in order to resolve the namespaces clashes between the environment variables in shell that launches setup_xml.py and the values used in config parm variables.

With this update the namespaces between the shell environment variables and the variables in parm files used by the Configuration Class are preserved. A Unit Test demonstrating this can be found here.

For example, if the environment variable ACCOUNT is set in the shell that setup_expt.py is launched from, it would would fail as that variable is also used in template of config.base. Correspondingly, if setup_xml.py was executed with ACCOUNT set in the shell it would populate the XML file with UNKOWN without erroring. With this update the value in the XML file would be set he value designated in the corresponding instantiated parm file config.base.

The Unit Tests specified below shows this failure does not occure and the updates are used in Test PR 2581

please activate the tests that are marked to skip in the GH runner.

@aerorahul Done: Configuration Unit Tests now pass in GitHub Runners with the update to the bash shell in the Subprocess. Also I updated the approach that solves the primary name classing issue with feedback from these tests that is now also more strait forward than before. Please re-review these changes. Thnx. ~T.McG
