Consistency in OBC variable naming convetions

I am using the boundary tools to generate OBC's for the Arctic domain from GLORYS. The options in the config file are great, but there is a difference in the naming convention for OBC's in the Arctic and other domains. For example, the temperature OBC's in the Arctic are temp_001 but the current scripts make thetao_001. These naming conventions also extend to the variables in the OBC files. It looks likewrite_glorys_boundary.py uses the GLORYS names for the files.

I think we could add a output name option in the config file, or we could convert the Arctic OBC's and xmls to use the names already in write_glorys_boundary.py. This issue is not urgent, but I think we should consider this to improve the consistency of our experiments across regions.
