Move a lot of configuration to a MySQL Database

[ryanteck]

MySQL Config considerations:

Firewall rule,
Create account that only has access to the lora database
Use Socket instead of port

Ok so:
After evaluating the size an MySQL Store would take up around 300-400MB which was unacceptable to store small config.

Experimented with SQLite but still wasn't the best. Soooo.....

All of the configuraiton is now in a YAML file, this was chosen for multiple reasons including readability and ease for expanding in the future. Lots of data is never planned to be stored in the file so should be perfectly fine.
