Add proper multi-server support

[joaodforce]

The current implementation of the BOT is not suitable to be used across multiple servers. The following topics should be addressed before it can do such thing:

• Implement server aware bill monitoring.
• Implement server aware configurations.
• Implement server aware LegiScan API Access.
• Implement a way to each server provide their own LegiScan API securely.

storing a separate database.json for each server would solve most of the issues. the file name could even be the server id.

Could get even more granular and have a database.json per channel. Including DMs.

That would be good for DMs, but not for servers. Servers might like a legiscan output channel and a legiscan config channel.
