[ENH] Products QA System

[app-generator]

Authenticated users are able to ask questions regarding a product

This is different from the support system and aims to extract a useful and specific QA section for each product.

Here is the flow:

• The guest user clicking on Ask a Question is invited to signIN
• Authenticated users are able to ask a question
• SUPERUSER provides an answer
• SUPERUSER can mark question to be public
• Public questions are added to the product page in the Q&A Section

By default the state is OPEN. The superusers can operate on the ticket, reply, and change state. Allowed states are:

• OPEN - feedback is needed from AppSeed stuff
• CLOSED - the question was answered

The superuser dashboard will have a menu item for this flow, filters & search.

@mominur-helios please take a look.

TY!
