refactor: Refactor & add required rapid response counterpart

[arslanashraf7]

Related Ticket:

#273

Description

We did some platform changes to use some of the rapid response functionality & later on we used to cherry-pick that with every Open edX release. Now we are trying to refactor and migrate all this code into a plugin in https://github.com/mitodl/open-edx-plugins.

What this PR does?

• It picks only the relevant parts of the commit(bbe7d06)
• It's currently in progress, But if we can move all the code to the plugin then this PR will contain the remaining counterpart.

How to test?

This should be tested once we create a rapid response plugin in https://github.com/mitodl/open-edx-plugins.

@pdpinch We've been adding the Rapid Responses tab in the instructor dashboard based on a condition if xBlockAside is added/enabled. Should I keep it like that or should I do it like something similar as we did for canvas integration e.g. Show the canvas tab if the plugin is not installed - (We removed a feature flag there)?

*Edit(17:56 GMT+5) Show the canvas tab if the plugin is installed

[pdpinch]

Yes, I think that's a better pattern and it would be good to be consistent.

[arslanashraf7]

Thanks. Updated my message above, I meant Show the canvas tab if the plugin is installed. But you already got it right I believe.

I don't think this comment is necessary

These inline imports aren't great for a few reasons. One reason is that if there's an import error, we wouldn't know until this function is called. I tried this locally and it seems to work.

Add this to the bottom of the imports at the top of the module:

rapid_response_enabled = 'ol_openedx_rapid_response.app.RapidResponsePluginConfig' in settings.INSTALLED_APPS
if rapid_response_enabled:
    from openedx.core.djangoapps.plugins.constants import ProjectType
    from edx_django_utils.plugins import get_plugins_view_context
    from ol_openedx_rapid_response.constants import RAPID_RESPONSE_PLUGIN_VIEW_NAME  # pylint: disable=import-error

Then update this block:

Suggested change

	if 'ol_openedx_rapid_response.app.RapidResponsePluginConfig' in settings.INSTALLED_APPS:
	from openedx.core.djangoapps.plugins.constants import ProjectType
	from edx_django_utils.plugins import get_plugins_view_context
	from ol_openedx_rapid_response.constants import RAPID_RESPONSE_PLUGIN_VIEW_NAME # pylint: disable=import-error
	if rapid_response_enabled:

I gave it a cleaner look instead of checking the plugin installation and then fetching the context we'll just fetch the context which will be a dict/None based on if the plugin is installed or not. Also, there has been an Upstream PR for making more general improvements and when that's merged we'll make our plugins context generic too.

@gsidebo This is ready for review again.

Looks great! Great job on finding get_plugins_view_context. That's so much cleaner than the conditional imports
