Duplicate host port

[hananiel]

Description

Using the extension method UseCloudHosting will ocassionally throw an exception similar to this: 'Failed to bind to address https://127.0.0.1:8083/: address already in use.'

This PR fixes the problem by adds additional filtering for various URL specification to detect duplicates and remove them. In addition when a wild card address is present, it will take precedence over specific ip addresses for a given port.

These changes do appear to fix the issue with no further change, but in my quick testing I think we can simplify further by completely removing references to ASPNETCORE_URLS
