Development: Support Pyris V2

[Hialus]

Checklist

General

• I tested all changes and their related features with all corresponding user types on a test server.
• Language: I followed the guidelines for inclusive, diversity-sensitive, and appreciative language.
• I chose a title conforming to the naming conventions for pull requests.

Server

• Important: I implemented the changes with a very good performance and prevented too many (unnecessary) database calls.
• I strictly followed the server coding and design guidelines.
• I added multiple integration tests (Spring) related to the features (with a high test coverage).
• I added pre-authorization annotations according to the guidelines and checked the course groups for all new REST Calls (security).
• I documented the Java code using JavaDoc style.

Client

• Important: I implemented the changes with a very good performance, prevented too many (unnecessary) REST calls and made sure the UI is responsive, even with large data.
• I strictly followed the client coding and design guidelines.
• Following the theming guidelines, I specified colors only in the theming variable files and checked that the changes look consistent in both the light and the dark theme.
• I added multiple integration tests (Jest) related to the features (with a high test coverage), while following the test guidelines.
• I added authorities to all new routes and checked the course groups for displaying navigation elements (links, buttons).
• I documented the TypeScript code using JSDoc style.
• I added multiple screenshots/screencasts of my UI changes.
• I translated all newly inserted strings into English and German.

Motivation and Context

The Iris WG has come to the conclusion that PyrisV1, which was based on guidance, is no longer the best way forward for Iris. So we decided that we should replace it with a new version called PyrisV2.
For this the entire Pyris Connector and the way responses are handled needs to be replaced in Artemis. This PR implements the first steps for proper PyrisV2 support.

Description

There are numerous changes that were needed:

• Entirely new PyrisV2 API that has to be supported with full DTO coverage
• Responses of Pyris now come in asynchronously via status updates
  • A list of active Pyris jobs in Hazelcast
  • Each job with a custom access token for security and easy identification
• New improved way to show the student what the progress of the pipeline is
• New mocking system for the server tests

The client will get some further changes in a future PR by @bassner.
The other features of Iris will be reenabled in future PRs.

Steps for Testing

Prerequisites:

• 1 Instructor
• 1 Programming exercise with the Iris Tutor Chat enabled

1. Log in to Artemis
2. Go to the exercise student page
3. Send a chat message -> You get status updates and a response
