* Introduce a new config 'enabled_port_drivers'. This config allows
operators to specify multiple port drivers to enable. This enables
Kuryr to dynamically choose from a list of port drivers (Veth or
SRIOV).
* Introduce a new SRIOV port driver for performing SRIOV port binding
* Choose port driver according to the type of the port. If the neutron
port has SRIOV vnic type, choose the SRIOV port driver. Otherwise,
choose the normal port driver (i.e. veth).
* To use this feature, users are supposed to pre-create a SRIOV port
and have the binding:profile populated. Furthermore, users should
pass the SRIOV port to Kuryr (i.e. using --mac-address <port_mac>
and/or --ip <port_ip> on 'docker run') so that Kuryr will choose
the right driver.
