Merge pull request #1567 from mnlevy1981/grids/fix_gx1v7_domain_dates…

…tamps

Point to gx1v7 domain files that exist - this is only relevant to cesm.

Test suite: N/A; I created the two cases that caused problems detailed in issue ticket, verified problem went away
Test baseline: N/A
Test namelist changes: N/A
Test status: bit-for-bit, except cases that previously died at runtime (or that CIME refused to submit) now run to completion

Fixes #1565

User interface changes?: N/A

Code review: verified that f09_f09_mg17 works for a A compset

Additional notes: @jedwards4b it looks like the pull request you reverted (#1559) also fixed #1558 -- I did not put that fix back in here.
