With this commit, we refactor the overall score handling of CodeOcean. Previously, "Score" and "Submit" were two distinct actions, requiring users to confirm the LTI transmission of their score (after assessing their submission). This yielded many questions and was unnecessary, since LTI parameters are no longer expiring after each use. Therefore, we can now transmit the current grade on each score run with the very same LTI parameters. As a consequence, the LTI consumer gets a more detailed history of the scores, enabling further analytical insights.
For users, the previous "Submit" button got replaced with a notification that is shown as soon as the full score got reached. Then, learners can decide to "finalize" their work on the given exercise, which will initiate a redirect to a follow-up action (as defined in the RedirectBehavior). This RedirectBehavior has also been unified and simplified for better readability.
As part of this refactoring, we rephrased the notifications and UX workflow of a) the LTI transmission, b) the finalization of an exercise (measured by reaching the full score) and c) the deadline handling (on time, within grace period, too late). Those information are now separately shown, potentially resulting in multiple notifications. As a side effect, they are much better maintainable, and the LTI transmission is more decoupled from this notification handling.
Previously, the same runner could be used multiple times with different submissions simultaneously. This, however, yielded errors, for example when one submission time oud (causing the running to be deleted) while another submission was still executed.
Admin actions, such as the shell, can be still executed regardless of any other code execution.

So far, a programming group is always considered to be a learner. While we could, technically, consider it to be a teacher or an admin if all members have this role, this behaviour might have unintended side effects.
* Correct sorting in table
* Modify page when nested in exercises
* Fix links between pages
* Link from statistics page to programming_groups/index
* Link from submission page to programming_groups/<id>
* Allow filtering for exercise ID on ProgrammingGroup#index
* Add search fields for internal and external user id on pg/index
For the submission and comments, I mainly decided to use a `has_one` association. Based on the database schema, multiple request for comments could be allowed (i.e., for each file or submission), but this won't happen practically (since we always create new submissions and files). Hence, the `has_one` association is representing our relationship better.
This change allows us to use the session ID immediately for the connection_change and connection_status methods. Hence, we can identify different browser sessions of the same user.
Previously, we were at an ACE editor published between 1.1.8 and 1.1.9. This caused multiple issues and was especially a problem for the upcoming pair programming feature. Further, updating ace is a long-time priority, see https://github.com/openHPI/codeocean/issues/250.
Now, we are not yet updating to the latest version, but rather to the next minor version. This already contains breaking changes, and we are currently interested to keep the number of changes as low as possible. Further updating ACE might be still a future task.
The new ACE version 1.2.0 is taken from this tag: https://github.com/ajaxorg/ace-builds/releases/tag/v1.2.0.
We are using the src build (not minified, not in the noconflict version), since the same was used before as well.
Further, we need to change our migration for storing editor events. Since the table is not yet used (in production), we also update the enum.
* This commit refactors the table used to store events.
* We also use a UUID as session identifier in the synchronized editor to support multiple concurrent tabs opened by the same user.
* Further, we renamed some methods to make them easier to distinguish.
* We want to identify a user that has triggered a testrun. Previously (in regular operation), only submission author who were regular users were able to start a testrun. Now, we want to prepare a future where submission authors are programming groups. Still, a testrun is triggered by an individual user and not a group.
* Further, this commit fixes some missing foreign key constrains.
