Update CIME to ESMCI cime5.8.2-2 (#2908)

Update CIME to ESMCI cime5.8.2-2

Squash merge of jgfouca/branch-for-to-acme-2019-05-06

Features
* Nuopc update
* nldas_forcing_v2: This is a regional, 0.125 degree data set over the U.S., for use in forcing CTSM.
* Change DATM_CLMNCEP_YR_ALIGN for present-day compsets: Make DATM_CLMNCEP_YR_ALIGN 
  match DATM_CLMNCEP_YR_START. This will make the model year align with the forcing year. For
  example, if RUN_STARTDATE is set to 2000-01-01, then the model will use year-2000 atmospheric 
  forcing data in the first year, etc. non-BFB for any present-day compsets using datm (mostly I-cases and G-cases).

Bug fix:
* Fixes to NAG flags in scripts/Tools/Makefile
