Add S3MessageHandler

Implement the `S3MessageHandler` based on the `TransferManager`.
Provide `upload`, `download` and `copy` operations.
Support single file upload/download as well as directory structure.
The `S3MessageHandler` may behave as `one-way`, as well as `request-reply` component.
The former is blocked, the second is async.

See test-cases and JavaDocs for more info.

/**
* The {@link AbstractReplyProducingMessageHandler} implementation for the Amazon S3 services.
* <p>
* The implementation is fully based on the {@link TransferManager} and support its {@code upload},
* {@code download} and {@code copy} operations which can be determined by the provided
* or evaluated via SpEL expression at runtime {@link S3MessageHandler.Command}.
* <p>
* This {@link AbstractReplyProducingMessageHandler} can behave as a "one-way" (by default) or
* "request-reply" component according to the {@link #produceReply} constructor argument.
* <p>
* The "one-way" behavior is also blocking, which is achieved with the {@link Transfer#waitForException()}
* invocation. Consider to use an async upstream hand off if this blocking behavior isn't appropriate.
* <p>
* The "request-reply" behavior is async and the {@link Transfer} result from the {@link TransferManager}
* operation is sent to the {@link #outputChannel}, assuming the transfer progress observation in the
* downstream flow.
* <p>
* The {@link S3ProgressListener} can be supplied to track the transfer progress.
* Also the listener can be populated into the returned {@link Transfer} afterwards in the downstream flow.
* * <p>
* For the upload operation the {@link UploadMetadataProvider} callback can be supplied to populate required
* {@link ObjectMetadata} options, as for a single entry, as well as for each file in directory to upload.
* <p>
* For the upload operation the {@link #objectAclExpression} can be provided to {@link AmazonS3#setObjectAcl}
* after the successful transfer.
* The supported SpEL result types are: {@link AccessControlList} or {@link CannedAccessControlList}.
* <p>
* For download operation the {@code payload} must be a {@link File} instance, representing a single file
* for downloaded content or directory to download all files from the S3 virtual directory.
* <p>
* An S3 Object {@code key} for upload and download can be determined by the provided
* {@link #keyExpression} or the {@link File#getName()} is used directly. The former has precedence.
* <p>
* For copy operation all {@link #keyExpression}, {@link #destinationBucketExpression} and
* {@link #destinationKeyExpression} are required and must not evaluate to {@code null}.
