This PR includes a number of minor fixes and updates associated with FATES.
A duplicate filter for all soils that was introduced during the the initial
implementation of FATES-SP mode is removed.  A small set of FATES history
variable names have been updated necessitating an update to the testmod
user namelists.  The ccs_config and cime externals have been updated to
include the FATES development workstation, lobata.  The cime tag update
is necessary to include a fix enabling support for module initilization
on certain linux distributions (https://github.com/ESMCI/cime/issues/4260).
Finally, a minor fix was included to the initialization of the fates_levcdam
dimension that was introduced with the last fates api update.
