admin.py testing. See previous checkin for admin.py. This got left out of the changeset apparently. test_admin.py: Add tests for get with bad node designator Add disabled test for HelpInitopts. Proper test TBD as valid result depends on the environment the test is run in. So making it robust it tricky. Add tests for set error cases. Add test for using set on class rather than designator Add new tests for table command
