Remove Eulerian dycore grids from our testing

[ekluzek]

What is the feature/what would you like to discuss?

As part of removing the Eulerian dycore (and even if the dycore isn't removed) I think we should remove the Eulerian grids from the testing or at least limit them to maybe one or two. These are the Eulerian tests in the testlist that I see now:

  <test compset="QPC4" grid="T42_T42_mg17" name="SCT_D_Ln7" testmods="cam/scm_prep">

Since we need to move these grids to use the MOM t232 land/ocean mask if these grids are kept we'll need to add grids for them into ccs_config that use the t232 mask rather than the POP mask (see #1236). I suggest that we don't do that and just shift all of the above grids to FV or SE grids.

Is there anyone in particular you want to be part of this conversation?

Will this change (regression test) answers?

No

Will you be implementing this enhancement yourself?

Any CAM SE can do this

@ekluzek - We have PR #1215 opened which is removing the EUL dycore. I've not taken a look at the details you've listed. Perhaps you and/or @brian-eaton who has opened the PR can make sure this PR has the required changes you've mentioned

[brian-eaton]

The Eulerian tests are removed in #1215. I'll add that this issue is resolved by that PR.
