Title:
  enable bridge command for openvswitch agent

Status in neutron:
  Fix Released

Bug description:
  Neutron's openvswitch agent has an extension called "fdb" that uses linux "bridge" command.
  currently, this command is not enabled for ovs agent by the wrootwrap filter.

  This is required to enable fdb extension, otherwise, we will encounter
  an unhandled exception:
