Merge pull request #1040 from adamrher/cam.L93v2

cam6_4_003:  replace L93 ncdata files w/ corrected versions. L93 hybrid coefficients had a discontinuous kink, or offset, creating an anomalously thin layer in the 300 hPa - 100 hPa altitude range. This region overlaps with the L58 grid, but for some reason the L58 grid didn't get contaminated like it was in L93. We aren't sure how this happened.

+One-line Summary: Corrected L93 default IC files
+Github PR URL: https://github.com/ESCOMP/CAM/pull/1040
+
+Purpose of changes (include the issue number and title text for each relevant GitHub issue):
+
+	The L93 hybrid coefficients had a discontinuous kink, or offset, creating an anomalously thin layer
+	in the 300 hPa - 100 hPa altitude range. This region overlaps with the L58 grid, but for some reason
+	the L58 grid didn't get contaminated like it was in L93. We aren't sure how this happened.
+	More here: https://github.com/ESCOMP/CAM/issues/1034
+
+	fixes #1034 - Problematic hybrid coefficients in L99
+
+Describe any changes made to build system: none
+
+Describe any changes made to the namelist: none
+
+List any changes to the defaults for the boundary datasets: Files with problematic hybrid coeff were
+	regenerated.
+
+Describe any substantial timing or memory changes: none
+
+Code reviewed by: cacraigucar, jet
+
+List all files eliminated:
+	Boundary data defaults eliminated from namelist_defaults_cam.xml (files still exist but will no longer be used)

+List all existing files that have been modified, and describe the changes:
+
+bld/namelist_files/namelist_defaults_cam.xml
+. Replaced problematic 93 level IC defaults with new files.
+
+If there were any failures reported from running test_driver.sh on any test
+platform, and checkin with these failures has been OK'd by the gatekeeper,
+then copy the lines from the td.*.status files for the failed tests to the
+appropriate machine below.  All failed tests must be justified.
