The previous commit laid out the foundation of the quota engine, this one builds on top of it, and implements the actual enforcement. Enforcement happens at the route decoration level, whenever possible. In case of the API, when over quota, a 413 error is returned, with an appropriate JSON payload. In case of web routes, a 413 HTML page is rendered with similar information. This implementation is for a **soft quota**: quota usage is checked before an operation is to be performed, and the operation is *only* denied if the user is already over quota. This makes it possible to go over quota, but has the significant advantage of being practically implementable within the current Forgejo architecture. The goal of enforcement is to deny actions that can make the user go over quota, and allow the rest. As such, deleting things should - in almost all cases - be possible. A prime exemption is deleting files via the web ui: that creates a new commit, which in turn increases repo size, thus, is denied if the user is over quota. Limitations ----------- Because we generally work at a route decorator level, and rarely look *into* the operation itself, `size:repos:public` and `size:repos:private` are not enforced at this level, the engine enforces against `size:repos:all`. This will be improved in the future. AGit does not play very well with this system, because AGit PRs count toward the repo they're opened against, while in the GitHub-style fork + pull model, it counts against the fork. This too, can be improved in the future. There's very little done on the UI side to guard against going over quota. What this patch implements, is enforcement, not prevention. The UI will still let you *try* operations that *will* result in a denial. Signed-off-by: Gergely Nagy <forgejo@gergo.csillger.hu>
