Run scm fixes (#1244)

Fixed error output for run?scm?all.bash, added some missing error checks to CLUBB
CLUBB ticket #975

* Fixed error output issues for run_scm_all.bash
- Changed tail $TMP_OUT to cat $TMP_OUT so we can see the entire stderr output of CLUBB in the log
- Added `if allocated` check to subroutine finalize_t_dependent_forcings in time_dependent_input.F90 to avoid runtime errors
- Removed unnecessary write statement in clubb_standalone.F90

* Added missing err_code checks
- Added err_code checks so we don't get false negative error messages

I am adding a new .json file for host model flags. Flag set 1 consists
of the current CAM default settings.

I am adding a Jenkinsfile for a new CLUBB generalized vertical
grid test that uses flag sets consisting of specialized flag
settings that are found in host models of which CLUBB is a part.

I am adding a second set of host flags as part of the generalized
vertical grid test for host model flags. Flag set 2 consists of
flag settings that are found in the clubb_silhs_devel branch of CAM.

Fixing an error in the previous commit. (lol, good ol' find and replace)
