Best practice: Split migrations into a standalone package

1. Move main.go into your cmd/ directory

2. Rename package name in all *_.go migration files from main to migrations.

3. Import this migrations package from your custom cmd/main.go file:

   import (
       // Invoke init() functions within migrations pkg.
       _ "github.com/pressly/goose/example/migrations-go"
   )
