    allow tcp-based consoles in get_console_output
    
    Tcp based consoles already offer a logfile but the information
    resides in a different path in the hosts XML. This change adds
    an additional xpath for tcp-based consoles.

Title:
  WS-based serial port proxy prevents access to console log file

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  This bug occurs with interactive WS-based serial ports in nova. The serial
  console on the Websocket works fine, but configuring these consoles
  prevents access to the console logfile via 'openstack console log show'.
  This bug was discovered in pike with KVM-based virtualization but seems to
  be in current master as well.

  Access to the console logfile is very important because my websocket
  client is usually not permanently connected.

  Detailed analysis:
  The console logfile is still generated by KVM/libvirt. The only difference
  is that the path of the logfile node changed in the XML information for
  the instance. The relevant function get_console_output() in
  nova/virt/libvirt/driver.py fails to find the logfile (it just looks for
  @type='file', it should also look for @type='tcp').

  I'll try to provide a fix for this myself, it shouldn't be
  complicated.

  Any comments?
