Look into dockerizing database

[NBurley93]

Right now we have an offsite database that we store user info onto. In the future, it would be more beneficial to have a database running as a dockerized container in the same stack as the bot. Persistent storage can be done with docker volumes, and this would ensure that the bot could theoretically be deployed anywhere that has docker installed.

Completion Criteria:

• [ ] Docker-compose now includes a service to provide MySQL and provision connection between DB and Bot services
• [ ] Bot service is updated to utilize connected docker service. This should be done already using the github secrets.

How does the interface between container and volume work?
