Iris: Load default templates from resource folder

Checklist

General

• This is a small issue that I tested locally and was confirmed by another developer on a test server.

Server

• Important: I implemented the changes with a very good performance and prevented too many (unnecessary) database calls.
• I followed the coding and design guidelines.
• I added pre-authorization annotations according to the guidelines and checked the course groups for all new REST Calls (security).

Motivation and Context

The current solution for default Iris templates is to put them all into a single static utility class, IrisConstants.java. This is not scalable, offers no syntax highlighting, and forces the system to be recompiled every time a default template is changed.

Description

Each default Iris template now gets its own .hbs (handlebars) file in the resources/templates/iris folder. The files are loaded using the IrisDefaultTemplateService, which uses the ResourceLoaderService to access the file with the requested filename in the folder. The IrisSettingsService then uses this service to load the default templates into the global settings at application startup.
The global template version used to be a static int field in IrisConstants, and this has also gotten its own file next to the templates. The content of this file is supposed to be just a single int and incremented every time one of the templates is adapted to trigger a reload from the files on application startup.

Please let me know if I have followed all best practices here!

Steps for Testing

Prerequisites:

• 1 Administrator

1. Log in to Artemis
2. Navigate to Server Administration -> Global Iris Settings
3. Ensure that the contents of each template file have been loaded into their corresponding text areas in the settings, e.g. chat.hbs -> chat settings, hestia.hbs -> hestia settings, and the same for all code editor files.

I don't see the "Global Iris Settings" Option under Server Administration:

Is some step required to make it appear?

I also don't see it. :/
Also, the E2E tests on Bamboo fail, take a look at that please:)

@xHadie @dearjasmina Sorry! The iris settings are available only on TS9, I forgot to mention that. It is deployed there right now if you want to have a look. I will also take a look at why the tests are failing 🤔
