Install-Module should offer client certificate authentication

[tylermontneyacc]

Summary of the new feature / enhancement

For instance, my private NuGet server requires a client certificate. I cannot specify this with ~~Install-Package~~ Install-Module.

Proposed technical implementation details (optional)

As far as I can tell, ~~Install-Package~~ Install-Module calls Invoke-WebRequest. This cmdlet does support client certificate authentication, which should be a simple pass through.

@tylermontneyacc thanks for the suggestion! This would be a great feature to have, but unfortunately we probably won't be able to get to this issue anytime soon. We'll likely be able to look into this once we GA PowerShellGet v3 and work on adding some more new features to the module.
