removal of ovsdpdk agent

[sean mooney]

following completion of https://bugs.launchpad.net/neutron/+bug/1469871
and the merger of https://review.openstack.org/#/c/197210/

the ovsdpdk neutron agent is no longer required to manage ovs with dpdk.

this bug tracks the removal of our forked agent and deployment code and documenting the
appropriate local.conf options to configure the standard neutron openvswitch agent to mange ovs-dpdk.

following this change the networking-ovs-dpdk repo will continue to provide the ml2 mechanism driver and
deployment code for compiling and installing ovs-dpdk.
