Following the python guidelines of usage, the operator's Dockerfile has been updated, to use a requirements.txt outside the dockerfile.

Identation fixes

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.

The source code directory has been moved from ./build to ./src.

This change was made to improve project organization and follow best practices.
