It would be easy to add tags to questions to easily find them.

Schema

tags
id | name | createdBy | createdAt | updatedAt

question_tags
id | tagId | questionId | createdAt | updatedAt

API to implement

• POST /tags
• GET /tags
• Make sure we can include tag with questions. i.e they are related
• Make the /questions api support filter: { tags: [ 12, 34 ] } query param.

The frontend part of this feature is explained here: coding-blocks/trouble-maker-frontend#18 and the bounty is for combined feature implementation.
