    Add cop for use of remove_column · 1ab33b15

    remove_column should only be used in the up (or change) step of a migration if
    it's a post-deployment migration. Otherwise there will be downtime due to the
    ActiveRecord column cache, which we can avoid by using the IgnorableColumn
    concern in combination with a post-deployment migration.
