Ask for proxy credentials in modal dialog

If a proxy requires authentication, DownloadFileTask will throw an
exception of type ProxyAuthenticationRequiredException. This exception
is handled in MetadataJob to first ask the user for credentials,
storing them in PackageManagerProxyFactory, and then retriggering
the download.
