      Runs servers defined in nova.yml.  If the forgeground
      option is specified, the process is run in the foreground.
      Otherwise, it's ran as a daemon.  If the which parameter is
      specified, it only runs the servers that were specified.

      Options that can be defined for servers include:

        :name    :: the name of the server.  Used to name the pid
                    files and the log files.

        :type    :: the type of server.  Can be :tcp or :unix.  If
                    it's :tcp, options :ip and :port can be defined
                    and will be used.  If it's :unix, the option :path
                    can be defined for the path to the socket.
                    Defaults to :tcp.

        :host    :: the IP address to bind to.  Only applicable if
                    :type is :tcp.  Defaults to

        :port    :: the port to bind to.  Only applicable if :type is
                    :tcp.  Defaults to 2010.

        :path    :: the path to the UNIX socket.  Only applicable if
                    :type is :unix.  Defaults to /tmp/sock.

        :protocol:: protocol options, used for settings in the
                    protocol. only current option is :allow_plaintext,
                    which prevents the server from raising an
                    exception if the  protocol negotiates a plaintext
                    encryption (insecure).
