Add execution script for vIPSec in k8s

Add execution scripts for each component in vIPSec to make it work for k8s.
These scripts are going to be used along with the helm chart named 'vipsec'
inside the demo folder.
It aims to construct the vIPSec use case to set up a secure tunnel between
peers and improve its performance along with hardware acceleration
technologies such as SRIOV and QAT.
