Category API

[aruizeac]

Is your feature request related to a problem? Please describe.
There is no way to fetch important data like authors and media with their respective categories. Categorizing them would be the best way to achieve our current milestones and strategic objectives.

Describe the solution you'd like
Along with Apache Solr or Elasticsearch, we could develop a powerful category API so anyone can fetch their authors and media with a better experience.

In addition, the Category API could be used as a hashtag module like in popular social media. Thus, the following Trending API would be easier to implement.

Describe alternatives you've considered
None.

Additional context
No.
