Move Torrust-Tracker to Apache License 2.0 to Match Aquatic Tracker

^{Originally posted by da2ce7 October 30, 2022} Hello @WarmBeer,

I would like to propose that we change the license of this repository (Torrust Tracker) to the Apache License 2.0.

My primary motivation for promoting this change is to have bi-directional license comparably with the aquatic: high-performance open BitTorrent tracker.

Currently our license permits us to take code from aquatic's repository, however, we are not able to return the favor of allowing our code to be copied by @greatest-ape.

It should be noted that we in-fact already depend on some of aquatic's code by using the crate: UDP BitTorrent tracker protocol to support our udp tracker implementation.

Question: Are there any real benefits for using the AGPL for Torrust-Tracker?

Question: Do you support the idea of moving Torrust Tracker to the "Apache License 2.0" and are also happy to change the license of your contributions in support ?
