maint-5.6 added support for new OMIP compsets in POP as well as better handling
of the different versions of JRA forcings. Unfortunately, a lot of these
changes conflicted with other updates to master and the original merge couldn't
be tested because the POP changes weren't available on master yet. I brought
the POP changes from cesm2_1_x_rel to master, and these were the CIME changes
necessary to run the aux_pop and aux_pop_MARBL testlists:

  1. Support the JRA025v2 grid
  2. Properly configure POP for compsets with longnames that start with OMIP
  3. Support DATM_CO2_TSERIES=omip
    -- required converting fco2_datm_global_ssp585_simyr_1750-2020_CMIP6 file
    from netcdf-4 to cdf5
  4. Remove CORE_IAF_JRA.CORE2.ArcFactor
  5. Remove extra rof.iaf_jra block from namelist_definition_drof.xml
  6. Update CCSM_CO2_PPMV default value for POP ecosystem from 284.7 to 284.317
    unless specifying ECOCESM20

[ Description of the changes in this Pull Request. It should be enough
information for someone not following this development to understand.
Lines should be wrapped at about 72 characters. Please also update
the CIME documentation, if necessary, in doc/source/rst and indicate
below if you need to have the gh-pages html regenerated.]

Test suite: aux_pop and aux_pop_MARBL using POP from ESCOMP/POP2-CESM#25
Test baseline: cime5.8.17 and cesm_pop_2_1_20200318 tags
Test namelist changes:
Test status: climate changing for specific C and G compsets, bit-for-bit (I think) for both fully coupled and any compsets with docn or MOM instead of POP

Update gh-pages html (Y/N)?: N

Code review:

I'd like @klindsay28 to look this over and give it a green light before it gets merged

Is this PR ready to be merged?

Not yet -- @klindsay28 and I have a code review scheduled for tomorrow afternoon and I'll update this PR afterwards

co2tseries.omip isn't used with any JRA v1.3 compsets (none of them have ocean
ecosystem turned on), so no need to specify stream_align for that case.
