…to read now and makes it shorter. Update the build-namelist unit tester and show that the clm4_5, clm5_0, and clm5_1 tests are all identical

Update to ctsm5.1.dev174

Update to newer tag. Which also includes an externals
update which broke the build/run of mksurfdata_esmf.
As a result I added some additional unit-testing in
order to detect this sort of thing sooner.

Use line return in place of ; in shell examples. Add some links

Remove nvhpc test from ctsm_sci since not

test as it's experimental and requires a huge
number of processors.

…jobscript so the test case is completely self-contained

Move the ne30 tests that were in the
cesm3_dev test list to the aux_clm.
And remove the cesm3_dev testlist.

…and aux_cime_baselines tests are run in aux_clm

…t so can make a ctsm5.2.0 tag
