Having a huge array to whitelist options is not the proper way to handle this case. This means that the ActiveModel::Errors object should know about the options given in *all* validators and break the extensibility added by the validators itself. If the intent is to whitelist options before sending them to I18n, each validator should clean its respective options instead of throwing the responsibility to the Errors object.
This reverts commit bc1c8d58ec.
This makes it possible to pass additional options through Validators to message
generation. E.g. plugin authors want to add validates_presence_of :foo, :format
=> "some format".
Also, cleanup the :default vs :message options confusion in ActiveModel
validation message generation.
Also, deprecate ActiveModel::Errors#add_on_blank(attributes, custom_message) in
favor of ActiveModel::Errors#add_on_blank(attributes, options).
