What official testing is required before merging?

A ton. We have to add this to the ufs-weather-model commit queue (with corresponding PRs in fv3atm and ufs-weather-model to handle the submodule pointer updates), run regression tests on all tier-1 platforms and CI tests. You don't need to worry, since your PR is so small I will combine it with other changes and handle the submodule pointer updates.

Note however that the CCPP rules do not allow writing to stdout/stderr directly. Instead, an error message needs to be populated with the corresponding information, an error flag set to 1 and the code needs to return. The CCPP framework then escalated this to the host model, which writes out the error message and aborts.

Making this change is beyond the purpose of this PR, but it is important that we work towards this capability in he future. It needs to work with UFS_UTILS and at the same time be in compliance with NCO error reporting standards.
