This commit adds a new automation script for creating topics. It's very similar to the existing 'create a post' automation, except that it posts new topics in a specific category and with optional tags.
Internal topic: t/125829.
The complexity of the situation is that we don't want to load faker into production by default but fabricators and styleguide are available on production.
This is made possible through app/assets/javascripts/discourse/app/lib/load-faker.js which contains a function to ensure faker is loaded asynchronously (loadFaker) and another function to access the loaded faker (getLoadedFaker).
Note 1: this commit also refactors fabricators to have access to context and use faker where possible
Note 2: this commit moves automation to admin bundle
