create training basics --> implement take training feature and resume training feature for user

[amitupreti]

What?

Here i have added a feature that will allow users to take the training from settings. User can choose from a list of available
trainings and take the onplatform training. Users can also see the progress of the training and can resume the training from where they left off.

Why?

This is a follow up PR for #1950

How?

Here we create 3 new views to handle the training.

1. training.views.take_training

This view will take care of training homepage. It will show progress of the training if the user has already started the training, show them details of the training and allow them to start/resume and review the training.

2. training.views.take_module_training

This view will take care of letting users take individual modules of the training. It will allow users to take the module from where they left off.
Users will need to finish module1 before they can start module2 and so on.

Here we have used a considerable amount of javascript to make the training interactive. How it works is when the user loads the module page,
we initially load all the content, quizzes and order them based on the order field, and initially we hide all the content and quizzes.

Then we show either the first content,quiz or the next one after a content, quiz that they had completed last time. and we keep doing this until the user has completed the module.

3. training.views.update_module_progress

This view uses a simple post request and expects an ajax request from the client. It will update the progress of the module and the progress of the training.

Testing? [WIP]

Following tests will be added

1. Check access to the training homepage
2. Check access to the training module page
3. Check valid and invalid submission of the training module
4. Check valid and invalid submission of the training

Screenshots (optional)

Anything Else?

How to take a training as a user?

1. Login as user
2. Navigate to Settings
3. Select the training from the dropdown
4. Start the training

Quick Note: There is a weird bug i just noticed

Currently OnPlatform training is treated unique based on version_number and training_type. So if a user had taken a training with version 1.1, and then next month there is a minor update with version 1.2, their previous training would still be valid.

But if they go and they try to review the training again, they will be retaking the new version 1.2 of training.(because by default we always provide them with the latest version of training).

Which brings to the weird bug which is that if the user hadn't finished the training 1.1 and the version 1.2 was lunched, then when they try to resume the training, it will be like taking the training from scratch for them

I merged this PR on top of #1950 to do some testing. There were a few issues I came across while testing:

1. Duplicate training:

Minor thing, but it is currently possible to upload duplicate training courses at:
http://localhost:8000/console/courses/

2. Getting stuck after hitting "back"

• Sign in and start a training course at: http://localhost:8000/settings/training/
• Click "Start" to start the training
• Click "Next" after reading the explanatory content on "The Americas"
• Select a response to the first question, then click "Back"
• "Next" is greyed out and cannot be clicked. You are stuck!

3. Reloading the page after following point 2 above

Reloading the page after following the points above triggers the following error. Returning to http://localhost:8000/settings/platform-training/3/ and clicking "Continue" triggers the same error.

Request Method: GET
Request URL: http://localhost:8000/settings/platform-training/3/module/3/

Exception Type: AttributeError at /settings/platform-training/3/module/3/
Exception Value: 'ModuleProgress' object has no attribute 'get_next_content_or_quiz'

4. Reviewing a completed course

After completing a course, returning to http://localhost:8000/settings/platform-training/3/ and clicking "Review" triggers the same Exception Value: 'ModuleProgress' object has no attribute 'get_next_content_or_quiz' error.

Thanks for running through this today @Rutvikrj26. As discussed, please could you remove all javascript elements as far as possible? If dynamic features are needed, consider HTMX.

@bemoody I've updated the URL for the heading and the PR is ready for further review / merge.
