Remove or convert legacy tests

[edwardhartnett]

I see we have some tests. We need to get them running with cmake not with scripts, and have them run by the CI.

See NOAA-EMC/NCEPLIBS#130

OK, there are a bunch of scripts which do some complicated stuff for testing:

  -rwxrwxr-x 1 ed ed  741 Dec 12 06:42 run_all_tests.sh
  -rwxrwxr-x 1 ed ed  736 Dec 12 06:42 run_all_tests_theia.sh
  -rwxrwxr-x 1 ed ed 4909 Dec 12 06:42 test_cnvgrib_theia.sh
  -rwxrwxr-x 1 ed ed 4566 Dec 12 06:42 test_cnvgrib_wcoss.sh
  -rwxrwxr-x 1 ed ed 7123 Dec 12 06:42 test_copygb2_theia.sh
  -rwxrwxr-x 1 ed ed 6818 Dec 12 06:42 test_copygb2_wcoss.sh
  -rwxrwxr-x 1 ed ed 4414 Dec 12 06:42 test_nam_file_cnvgrib_theia.sh
  -rwxrwxr-x 1 ed ed 4049 Dec 12 06:42 test_nam_file_cnvgrib_wcoss.sh
  -rwxrwxr-x 1 ed ed 7648 Dec 12 06:42 test_wgrib2_theia.sh
  -rwxrwxr-x 1 ed ed 7413 Dec 12 06:42 test_wgrib2_wcoss.sh
  -rwxrwxr-x 1 ed ed 3475 Dec 12 06:42 test_wgrib_wcoss.sh

When I look at these tests, they seem to use some data already existing on wcoss/theia. They run some of the grib_util commands but don't seem to check the output - if the command completes, then the test passes.

Looks like these tests will be too difficult to recover and will be removed. @BoiVuong-NOAA if you would like to attempt to recover these tests and keep them in use:

• The data files must be small and committed to the tests directory.
• The test must not be machine specific, but run on all Unix machines.
• The test must check output for correctness, not just assume everything worked if there is not a crash. ;-)
