Use console information from DBUS

This drop is a preparation of supporting multiple consoles in bmcweb.
In this drop we will hook up the new DBUS interface to get the unix
socket file descriptor for existing host console. At this time bmcweb
only allows host console.

This drop includes following bmcweb changes:
  - The default console leaf node is set to "default" by the obmc-console
  - Currently the URL is still maintained to /console0 for GUI
    compatibility. In future, it will be changed to /console/<str>
    where <str> could be any string which represents the console id.
  - In the obmc routing function, query the console DBUS interface for
    all available consoles. If the object leaf matches with the target
    string, then create socket and assign the file descriptor returned
    by the DBUS console.

Testing:
    Make sure that console open is working for /console0 on rainier machine
