Drop all tests that seem to be testing the superclass

I changed configuration_script_source.rb to:

```ruby
class ManageIQ::Providers::EmbeddedTerraform::AutomationManager::ConfigurationScriptSource < ManageIQ::Providers::EmbeddedAutomationManager::ConfigurationScriptSource
  FRIENDLY_NAME = "Embedded Terraform Repository".freeze

  def sync
  end
end
```

and all of the removed tests still pass which tells me either the tests
aren't needed, the code needs to be implemented and/or the test needs
to test what unique behavior is provided by this class.
