Add a check for MOM6 parameter filenames defined in input.nml

[jo-basevi]

In this branch, I've tagged on some code that runs at the end of Mom6.setup() that checks if files listed in parameter_file of MOM_input_nml and SIS_input_nml namelists in input.nml, are included in mom6's hard coded config_files or optional_config_files.

If the file is not present, I've added a warning, added the file to config_files and then copied the file to the workpath.
Or is just a warning/error printed out during setup sufficient? If not, should the files be treated as config_files or optional_config_files - i.e. raises an exception if file not found or not?

From what I can tell, the only usages of optional_config_files and config_files are:

• to be added to the runlog manifest (which happens during Experiment.run())
• config files are copied from the control path to the work path (at Model.setup())

Should close #325

I would have asked @angus-g for a review, but he wasn't a team member. Have added him, so he should be able to review this.

I've pinged you for a review @angus-g

This is a much nicer way of dealing with things! I've left a comment on how to take this a bit further to tidy up the lists of config files.

Excellent, thanks @jo-basevi, this looks good now!
