- Bot now takes shard id (optional) and total shards (optional) command line arguments (changed from shard id and parent process id)

- Sharding with coordinator now works properly
- Documented creds.yml RestartCommand - it has no effect when coordinator is starting the bot
- Regenerated creds_example.yml
- Removed all db migrators as the v3 requires the user to have updated 2.x all the way
- TotalShards in creds.yml gets overriden by coord.yml's TotalShards if the bot is ran through coordinator (more precisely, by the command line argument to the bot)
- Coordinator now runs on http://localhost:3442 by default, you can change this in appsettings.json
    - This is done because of macos https issues
    - Primarily because https for regular users is a massive hassle. Coordinator shouldn't be exposed anyway
- Minor cleanup
