[lixuna]

convert Docker CNF to work on K8s

• create base template and values files based on Docker code
• Debug VPP failures dpdk start up
  • Quick fix disable additional sockets in host to resolve NUMA zone
• templating for cpu pinning
• templating and config map for memif sockets
• Implement alternative for NUMA zone isolation in the CNF
