Spring Fix meta-annotations: @Timed and @Repeat

The javadoc of the annotations @Timed & @Repeat says: "This annotation may be used as a meta-annotation to create custom composed annotations."

The @Inherited annotation is missing in the definitions of both annotation. We should add the @Inherited annotation to make them meta-annotations or update the javadoc.

// Steps to reproduce the problem:

@Timed(millis = 5000L)
@Retention(RUNTIME)
@Target(TYPE)
@interface MetaAnnotation {}

@MetaAnnotation
class TargetClass {
}

Timed timed = TargetClass.class.getAnnotation(Timed.class);
// timed is null

The @Inherited annotation has no effect on whether an annotation can be used as a meta-annotation. Thus, the Javadoc is correct.

The fact that @Timed and @Repeat are both meta-annotated with @Target({ElementType.METHOD, ElementType.ANNOTATION_TYPE}) allows them to be declared on other annotations (i.e., "used as a meta-annotation").

Class#getAnnotation(...) does not support lookups of meta-annotations.

If you want meta-annotation support, you would need to use one of Spring's annotation search algorithms that supports it. For example, Spring itself uses org.springframework.test.annotation.TestAnnotationUtils to lookup @Timed and @Repeat via org.springframework.core.annotation.AnnotatedElementUtils.findMergedAnnotation(AnnotatedElement, Class<Timed>).

I am therefore closing this PR as invalid.
