This patch adds a source build of DPDK 17.11.5 to the openvswitch image
and enables DPDK during build time of openvswitch. Moreover, it bumps
the version of openvswitch from 2.8.1 to 2.10.1.
This adds the building of the images present in the OpenStack-Helm
Images follow the same process as images from the osh-infra
Kubernetes-entrypoint is not used anymore and therefore was
not migrated over.
Likewise, LOCI is not following these images building process,
and therefore will be included in a different patch.
The manual build script do not expose the extra arguments
previously exposed, like KUBE_VERSION or OVS_VERSION by default.
It also means a future tagged version of this repository will
use the KUBE_VERSION or OVS_VERSION that are in tree, and
therefore very explicit.
