Best practice: Split migrations into a standalone package

1. Move main.go into your src/cmd/ directory

2. Adjust the imports to the paths for your project

3. Create src/migrations/ directory with your migrations named #######_migration_name.go with the package declared as migrations.

4. Build the go package: $ go build -o goose src/cmd/*.go
