[last PR stuff] + Add warning if configs specified in 2 params (#5)

* Lean on API validation for tower_inventory_source arg errors

used for
 - validating needed credential is given
 - missing source_project for scm sources

* Add warning when config is specified in 2 places

Fix up unit tests, address multiple comments re: backwards compatibility, redundant methods, etc.

Update new_name and variables parameters, update unit tests
