Howdoi flask app fixture

[joeyouss]

Description

(Describe in detail what you want to work on) Howdoi has a flask app which is currently broken due to the usage of older version. With this issue, we propose a new flask app which would contain howdoi video ( hence created for showing howdoi features ) and the main app.
