Add VERSION file and update release scripts

 • Introduced a VERSION file to track the release version.
 • Simplified the release-autoscaler.sh script by removing hardcoded variables and adding a new create_mtar function for building mtar artifacts.
 • Added local_release_autoscaler.sh script to facilitate local testing and release process, including automatic SSH key generation and cleanup tasks.
 • Updated changelog generation to include mtar artifact details.
