Allows for customization of the application's Environment prior to the application context being refreshed. 
 EnvironmentPostProcessor implementations have to be registered in META-INF/spring.factories, using the fully qualified name of this class as the key. 
 EnvironmentPostProcessor processors are encouraged to detect whether Spring's Ordered interface has been implemented or if the @Order annotation is present and to sort instances accordingly if so prior to invocation.
