aux_cdeps test using f19_g17_rx1 fails, because no longer defined in ccs_config

[ekluzek]

The drof test in aux_cdeps using the f19_g17_rx1 grid alias fails because it's no longer defined in ccs_config. The exact test is:

SMS_Ld3.f19_g17_rx1.2000_SATM_SLND_SICE_SOCN_DROF%NYF_SGLC_SWAV.derecho_intel

PR #343 ran into this in it's testing

The grids that could be used that have rx1 explicitly are only old ones that support POP grids:

  <model_grid alias="T31_g37_rx1" compset="_DROF" not_compset="_MOM">
  <model_grid alias="f45_g37_rx1" compset="_DROF" not_compset="_MOM">
  <model_grid alias="f45_g37_rx1" compset="_DROF" not_compset="_MOM">
  <model_grid alias="f45_g37_rx1" compset="_DROF" not_compset="_MOM">
  <model_grid alias="ne30_g16_rx1" compset="_DROF" not_compset="_MOM">
  <model_grid alias="ne30_g16_rx1" compset="_DROF" not_compset="_MOM">

But, we are proposing to standardize the names for them to have the rx1 after the atm grid. And the older g16 grids for ocean shouldn't be used.

However, for example, f19_g17 could be used, because it should figure out that DROF will use the rx1 grid.

Since we no longer support POP and the standard CAM grid is now the SE dycore. The grid to use is probably this one:
