Verify command packages have the wheel extension applied

[Derek Bekoe (derekbekoe)]

Verifies the following as part of CI:

A valid command module .whl for the CLI should:

• Not contain any init.py files in directories above azure.cli.command_modules.

Does the package have a azure_bdist_wheel.py file?
Does the package have a setup.cfg file?
Does setup.py include 'cmdclass=cmdclass'?

Johan Stenberg (ex-msft) (@johanste) Does this look good to you?

[Johan Stenberg (ex-msft) (johanste)]

Technically, using path.join is the right thing to do.

[Johan Stenberg (ex-msft) (johanste)]

One minor nitpick. Other than that, looks good. You could consider printing which init.py file was included in the package, but that is not required (it's not that hard to crack open the wheel after all)
