Changelog:

• Restructured repo.
  • udfgen module moved to mipengine to remove dependency of the controller from the node.
  • common and utils module removed in favor of a more flat structure.
  • monetdb_dockerized renamed to monetd and removed config folder.
  • Moved demo_data in the tests folder. It will be used from integration and e2e tests.
• Improved the config files to use env variables, so that dockerized services can pass them values directly.
• Fixed the controller to use config file to read the CONSUL IP and PORT.
• Dockerized the NODE and CONTROLLER services
• Added e2e tests (get_algorithms, post_algorithm) to be run with the whole deployment stack.
• Added github actions for e2e tests where the services run dockerized.
• Added github actions to publish all dockerized packages when a release happens.
