Merge branch 'wlin/atm/80LRRM' (PR #6698)

Make L80 default for RRM grids

Change default RRM configurations from 72 to 80 levels.
L80 atm initial files for conusx4v1pg2 and northamericax4v1pg2 (narrm)
are added that are needed for nightly tests. The grid for narrm is changed to
northamericax4v1pg2_r025_IcoswISC30E3r5 as used for v3 narrm production config.
The testing PE layout is increased to 128 tasks (PS) to 512 tasks.

[non-BFB] only for the conusx4v1pg2 test. The NARRM test becomes a new test.
