PSGalleryModule - Make ApiKey optional

[ghost]

Similar to #72
Can we make the ApiKey parameter optional? Some repositories do not require a key, and this blocks me from being able to publish a module to our internal repository.

For that, the NuGetAPIKey parameter in the Publish-Module @params (Line 47 of PSGalleryModule.ps1) would need to be removed/modified.

Any thoughts on how you'd like to proceed?

Thanks!

I'm OK with making ApiKey an optional parameter. Thoughts @RamblingCookieMonster?

@commanderpoop, would you like to put in a PR with the changes?

Thanks for the ping @devblackops!

@commanderpoop - makes sense to me, if you're up for a pull request, that would be awesome! Maybe just remove mandatory param attribute, conditionally add to params hash?

Cheers!
