Merge tag 'ctsm5.1.dev065' into neon_modify_dev_0831

This tag refactors the static fire data input methodology to enable a future anthropogenic fire suppression
methodology to FATES as described NGEET/fates#673. This future method requires that FATES have access to
GDP data that was previously defined in CNVegStateType.F90 as part of cnveg_state_type.  As such, the GDP
variable has been moved into fire_base_type in FireDataBaseType.F90 to provide the data to the extended
fates_fire_base_type for eventual use in FATES.  Similarly, the surface dataset read subroutine has been
moved along with the peat and ag-fire variables, which utilize the same read subroutine and where also
originally part of the cnveg_state_type.

+CTSM now by default uses the NUOPC based CMEPS driver!

+## What's new?
+
+MESH Files:
+Mesh files to describe grids are new in both the driver namelist and for example in any
+streams files.
+Full ESMF Library is used:
+The full ESMF Library is used and required to be built in order to run the model.
+Single Point cases:
+Single point cases can now set their location using PTS_LAT and PTS_LON.
+
+## What's removed?
+
+Domain files are no longer used. And mapping for regriding is created on the fly
+rather than using fixed mapping files in almost all cases. Runoff mapping files
+still need to be generated offline.
+
+## What files change?
+
+rpointer.drv becomes rpointer.cpl
+cpl.log.* files get's split into med.log.* and drv.log.*
+user_datm.streams.txt.* file changes goes into the user_nl_datm_streams files
+datm.streams.txt.* files are all in one file called datm.streams.xml
+
+## What XML variables change in your case?
+
+DATM_CLMNCEP_YR_* variables change to DATM_YR_*
+
+## New obscure options:
+
+ESMF_AWARE_THREADING --- ESMF is aware of threading (can have differing number of threads in components)
+CREATE_ESMF_PET_FILES -- Create output log files from ESMF for each Processor (PET)
+ESMF_VERBOSITY_LEVEL --- Verbosity level for ESMF logging
+ESMF_PROFILING_LEVEL --- Verbosity level for ESMF profiling
+
+nuopc.runseq is a text file that determines how the driver operates. You can change the operation
+by having an updated copy in your case directory.
+
+
+## What if I want to use the previous MCT driver?
+
+The MCT driver will be available for sometime going forward, but
+new development won't go into it, and it will eventually be removed.
+But, if you have to...
+Use the "--driver mct" command line option to create_newcase
+You can set COMP_INTERFACE in a case as well, but it won't create it with everything needed
+so we recommend setting up a case from scratch.
