When used as global Netty resources, ReactorResourceFactory creates and
sets those resources on Reactor's HttpResources directly.
When that ReactorResourceFactory bean is destroyed, those resources are
disposed but HttpResources still holds a reference to those and may try
to use them again.
This commit uses HttpResources to clear those resources and its
references to it, when the ReactorResourceFactory is treating those as
global.

JettyResourceFactory, similar to ReactorResourceFactory, allows
to share resources (Executor, ByteBufferPool, Scheduler) between
Jetty clients and servers.

Prior to this commit, when using the `SimpleClientHttpRequestFactory`
as a driver for `RestTemplate`, the HTTP response body would only be
drained if there was an attempt to read it in the first place.
This commit ensures that, even if there's no attempt at reading the
response body, it is properly drained when the response is closed to
make sure that the connection is released in a proper state and can be
put back in the connection pool for reuse.

When dealing with `Optional` values in a Controller handler (for
example, values coming from a Spring Data repository), developers might
reuse this code snippet quite often:
```
@GetMapping("/user")
public ResponseEntity<Optional<User>> fetchUser() {
Optional<User> user = //...
return user.map(ResponseEntity::ok).orElse(notFound().build());
}
```
This commit adds a new static method on `ResponseEntity` for that,
simplifying the previous snippet with `return ResponseEntity.of(user);`
Note that in case more specific HTTP response headers are required by
the application, developers should use other static methods to
explicitly tell which headers should be used in each case.

Includes caching of declared annotation arrays and combined searching for several annotation types (used in SpringCacheAnnotationParser).
Issue: SPR-16933
Prior to this commit, if a test class was meta-annotated with multiple
@BootstrapWith declarations that registered different
TestContextBootstrapper implementations, such a configuration would
result in an IllegalStateException, and there was no way to override
this behavior.
This commit addresses this shortcoming by relaxing the explicit
TestContextBootstrapper resolution in BootstrapUtils so that a directly
present @BootstrapWith annotation will now override declarations of
@BootstrapWith that are meta-present. In other words, if @BootstrapWith
is used as a meta-annotation, it can be overridden directly on the test
class via an explicit, local declaration of @BootstrapWith.
