Update in response to ubuntu issues.
Remove -e for echo in test_facts_d
Removing tests from units that are now implemented in the new upgraded test system.  Once
we're a little further along the units directory will be reserved to pure-API tests.
Various tests using datafiles are being moved into the integration test framework (tests_new right now).

The unit test infrastructure will remain for things that are mocked out and testable with out filesystem
side effects, and a few cases of things that might not be quite so much (like inventory) that can still
benefit from heavy access to the API.

See the 'tests_new/integration' directory, this will soon fold into tests_new.
Move inventory tests into subdir, prune non-integration tests.
Adding a new test for the ping module
Add data test for ping
Move integration tests into tests_new.
Rename tests to test, use old directory name.
reconnect unit tests to 'make tests'
