Use mysql2 instead mysql

[murilomaiaa]

I'm using mysql2 to connect to the database but this library requires mysql. I think it'll be fine to use mysql2 or mysql not just mysql

@murilomaiaa - Thanks for the idea! Would be happy to consider implementing and supporting multiple mysql wrapper libraries. Though it would be greatly appreciated if you provide a abstracted factory implementation where based on the user dependencies we can build their environment with the tooling of their choice.
Like the idea :)
