fix(externalapi): extract basic auth and pass it through header (#1062)

This commit adds extraction of basic authentication credentials from the URL and then pass the
credentials as the `Authorization` header. And then credentials are removed from the URL before
being passed to fetch. This is done because fetch request cannot be constructed using a URL with
credentials

fix #1027
