SCM plugins often need to maintain a list of SCM servers, and as such need an API to take an URL and turn it into a reasonable suggestion of a display name to cover the cases where the user doesn't bother to provide a display name.

Acceptance criteria:

• The API will only process the hostname part of the supplied URLs
• In cases where no sensible name can be generated, the API returns a null response
• The API shall remove public TLDs and well known public SLDs from the hostname.
• The API will remove a caller provided list of well known prefixes from the hostname.
• The hostname shall be punycode decoded if necessary
