Automatically import widgets?

[lebouquetin]

In the galae website integration, the content body is in charge of including the widgets:

--- BODY (last / third) ---
{% from "widgets/page_block_h2_with_ul_content_and_image_left.html" import page_block_h2_with_ul_content_and_image_left %}
[...]

Expected:

• automatically inclusion of widgets in order to make them all available in all contents.
• maybe adda CLI command which list available widgets (and the associated file path)

Something like:

$ ./manage.py list-widgets

page_block_h2_with_ul_content_and_image_right(): ./common-content/templates/jinja2/widgets/page_block_h2_with_ul_content_and_image_right.html
page_block_h2_with_ul_content_and_image_left(): ./common-content/templates/jinja2/widgets/page_block_h2_with_ul_content_and_image_left.html
page_section_main_cta(): ./common-content/templates/jinja2/widgets/page_section_main_cta.html
