Override default +Jinx::Resource.merge_attributes+ to support the Capacity :rows and +:columns+
 pseudo-attributes.

 @quirk JRuby Subclasses do not pick up this class's Resource method overrides.
   Specimen picks up the AbstractSpecimen Resource overrides, but ContainerType subclasses do
   not pick up ContainerType Resource overrides. Work-around is that each ContainerType
   subclass must alias +merge_attributes+ to this method.
