This change updates all cases where callbacks are invoked to catch and
suppress errors (since there is not match to do with and error from
a callback be it success or failure).
Also updated is the contract itself to clarify this and emphasize the
callbacks are really notifications for the outcome of the
ListenableFuture not the callbacks themselves.
Issue: SPR-13785
Before this change AsyncRestTemplate had two anonymous implementations
of ListenableFuture that were adapting the result. Those have been
replaces with ListenableFutureAdapter.
This commit is preparation for SPR-13785.
Previously, any `javax.jms.Message` was converted eagerly to the Message
abstraction. This leads to unnecessary conversion if the Payload is not
requested by the underlying method (i.e. if the `javax.jms.Message` is
injected directly).
This commit returns a `Message` implementation that holds the
`javax.jms.Message` and lazily resolve the payload or the headers on
demand (that is the first time they are requested).

Prior to this change, a resource handler chain configured with a
`VersionResourceResolver` would add the resource version to the request
attributes when serving that resource. This approach would not work when
a `CachingResourceResolver` is configured and the resource is already
cached. Indeed, that code path is not executed when the resource is
resolved from the cache.
This commit adds a new `VersionedResource` interface that's used by the
`VersionResourceResolver`, adding a `getVersion()` method that returns
the version string for that resource. This way, the version information
is cached with the resource itself and the request attributes are no
longer used for this.
Issue: SPR-13817
Since ListenableFuture callbacks are invoked after the future is set,
we cannot rely on callbacks having taken place right after a call
to future.get(). This change adds a CountdownLatch to detect when
the callbacks were invoked.
Issue: SPR-12538
AsyncRequestExecution now properly supports decoration of the
request (URI, HTTP method, and headers).
Removed a no-op IdentityListenableFutureAdapter.
Use Spring Framework coding style.
