l2sm-switch: Updated initiation script for containerized process

Modified the switch subsystem to use a new initiation script that runs as a full process within the container. The script is now invoked using CMD in the Dockerfile, eliminating the direct creation of VXLANs. This change enhances the containerization approach and ensures a more streamlined and efficient initiation process.

This adjustment aligns with best practices for running processes within containers and improves the overall architecture of the switch subsystem.
