Adding PROX(Packet pROcessing eXecution engine) VNF to sampleVNF
JIRA: SAMPLEVNF-55
PROX is a DPDK-based application implementing Telco use-cases such as
a simplified BRAS/BNG, light-weight AFTR... It also allows configuring
finer grained network functions like QoS, Routing, load-balancing...
(We are moving PROX version v039 to sampleVNF
