When submitting a module build from scmurl, there is a check whether the URL has an allowed prefix. See this code snippet from views.py

url = self.data["scmurl"]
if not any(url.startswith(prefix) for prefix in conf.scmurls):
    log.error("The submitted scmurl %r is not allowed" % url)
    raise Forbidden("The submitted scmurl %s is not allowed" % url)

My question is why we want to check such thing? It would be nice if people could build from private servers - at least when MockModuleBuilder or CoprModuleBuilder is used.

If the check is not required, we may want to remove it. Otherwise I would suggest some bool ALLOW_CUSTOM_SCMURLS variable in config which may be by default False if you want and adding it to the code above.

Another option is to support regexes in those prefixes list and for custom scmurls adding just * or something, but I don't like this option very much.

What are your thoughts about that? I am willing to implement it (it is very simple though), but I need some context for it.
