Update httpd to build for release.

[Billy99]

Changes include:

• Added 'dpdk-app-centos' to the repo.
  • Move to use repo https://gitlab.com/mcoquelin/dpdk-next-virtio.git branch kubecon_vdpa_drivers, instead of upstream DPDK.
  • Add MAC from app-netutil to DPDK interface parameter.
  • Add '--single-file-segments' to DPDK parameter list.
  • add '--eth-dest 0,00:e8:ca:11:cc:01 --eth-dest 1,00:e8:ca:11:cc:02' to l3fwd app.
• Updated Makefile to support 'SCRATCH=y'.
• Removed 'make vdpa-cni-image' and 'make sriov-cni-image' because broken.
• Moved network-attachment-definitions to use vdpa-net-httpd, vdpa-net-l3fwd-a vdpa-net-l3fwd-b instead of vdpa-net-a, vdpa-net-b, vdpa-net-c.
• Move httpd image to build for 'release' instead of 'dev'.
• For httpd image, copy seawreck binary over and add flag to entrypoint.sh to work with both httpd and seawreck. Seawreck is crashing, so currently not supported, but infra is in place.
• Update httpd parameters to use only 1 CPU (CPU 4), and set the ipmask to 255.255.240.0.
• Update all images to no longer delete conf files after they process the data. On container restarts it was causing too much confusion. This includes:
  • vdpa-dpdk-image - entrypoint.sh - Don't remove /var/run/vdpa/pciList.dat
  • server-image - server.go - Don't remove /var/run/vdpa/socketList.dat
  • httpd-image - entrypoint.sh - Don't remove:
  • /var/run/seastar/seastar_dpdk_dynamic.conf
  • /var/run/seastar/seastar_ip_dynamic.conf
  • /var/run/seastar/seastar_seawreck.json
