  - Add a script to create proxies to dashboards

    A script to create virtual hosts in Apache2 to proxy communication to
    the web dashboards/consoles which might be on private networks. In case
    of frequent access to these services, this approach is simpler than
    using SSH tunneling each time.
    Additionally, this script creates a customized homepage for the jumphost
    with links to the dashboards and information about the credentials.
