Add reversible syntax for change_column_default
Passing `:from` and `:to` to `change_column_default` makes this command
reversible as user has defined its previous state.
So, instead of having the migration command as:
change_column_default(:posts, :state, "draft")
They can write it as:
change_column_default(:posts, :state, from: nil, to: "draft")
