Add question translation feature 🇬🇧

[viconnex]

Feature Request

Today a question may be shared between two question sets.
For example "thé ou café" may be related to TheodoFR and TheodoUS.
But actually this question is duplicated in two questions :

- {id: 1, option1: "thé", option2: "café"}
- {id: 2, option1: "tea", option2: "coffee"}

Which is quite painful for two reasons :

• for data reason : if you want to analyze people preference, you have to merge both solutions
• admin of TheodoUS or TheodoUK must duplicate questions instead of just translate them
• if a user switches its questionSet, the user will have to answer the same question again

Possible solution

• add two columns to the question entity option1EN, option2EN

{id: 1, option1: "thé", option2: "café", option1EN: "tea", option2EN: "coffee"}

• send these properties on questions/all, questions/asaskai endpoint (+ bonus : admin)
• fronend :
  • if getLocale results to EN and option1EN/option2EN are defined, display them, otherwise display option1 / option2
• si getLocale renvoie EN, afficher option1EN ou option1 si option1EN non définie
• in admin question edit view, enable to fill option1EN, option2EN
