Feature Request: Automatic API Key

[raynormast]

If we could set up pre-configured instances and API keys with docker it would allow easier integration of FakeRelay into other projects.

For instance,

   environment:
      - DEFAULT_HOST=https://my-pet-mastodon.com
      - DEFAULT_KEY=<SOME KEY I USED>

This would let me include FakeRelay in another docker-compose file without requiring other users to use FakeRelay's CLI to get started, they would only need to update the relays in their Mastodon instance.

This is interesting... but I'm wondering if using the /data volume wouldn't be enough. If you have the json files mounted there, things would just work. You can then have as many hosts as you want, and also stable private / public keys.
