Title:
  delete_tap_interface method is needed

Status in OpenStack Compute (Nova):
  Fix Released
Status in OpenStack Compute (nova) grizzly series:
  In Progress

Bug description:
  In nova using libvirt, there is a method to create tap interface under linux_net.py but there is not one for removing them.
  Usually, nova plougins use either the delete_ovs_vif_port that invokes OVS-specific commands and will not work in an environment OVS-free, and the second available option is under QuantumLinuxBridgeInterfaceDriver::unplug but this one is attached to linux bridge. So, there is not native call for removing a tap interface based on the dev name.
