Draft: Initial implementation of the optical cybersecurity loop

The changes are mainly to four components:

• DBSCANServing
• Optical Attack Manager
• Optical Attack Detector
• Optical Attack Mitigator

The changes include:

• Improvements in the names of the components, i.e., by removing the unnecessary "centralized" term
• Improvements to the building of images, now using a standard teraflow user for all images
• Inclusion of the .dockerignore file to prevent Docker to copy generated photo files
• Inclusion of the generation of async proto files needed for the attack manager
• Inclusion of the four components to the specification in my_deploy.sh
• Inclusion of the four services to the common.Constants file
• Update to specific Python 3.9 version
• Updates to the gitlab-ci yaml files

Still to do:

• Fix the tests of the optical attack manager
