Use internal OVS repo with patches for apidocgen
Use internal OVS repo with patches for apidocgen

ops-restd gate process generates the Swagger documentation using
apidocgen. This scripts uses the ops-openvswitch python libraries to
validate the content of the schema. However, ops-openvswitch needs some
patches applied by Yocto in build time (the code it was using was not
patched and therefore apidocgen.py was failing).

This fix make the swagger task use the openvswitch/ovs repo, which has
the patches applied.
