[5pt] Get gms_pipeline working. It will process gms_run_unit and gms_run_branch in one kickoff call

[RobHanna-NOAA]

The gms_pipline.sh file already exists and needs to be updated. Update parameters, add a few new ones, and remove some functionality (aka.. don't let it kick off some subsquent processing such as alpha test).

Also add a feature where after the gms_run_unit portion has been processed, count the number of unit log error files and figure out the percent pass/failed. If it surpasses a given percent, then do not continue to gms_run_branch.

This will make it easier for development and testing use, but also can be used in future enhancements such as the API V2 tool.
