/**
 * <p>
 * Contains options for setting the versioning configuration for a bucket.
 * </p>
 * <p>
 * A bucket's versioning configuration can be in one of three possible states:
 * <ul>
 * <li>{@link BucketVersioningConfiguration#OFF}
 * <li>{@link BucketVersioningConfiguration#ENABLED}
 * <li>{@link BucketVersioningConfiguration#SUSPENDED}
 * </ul>
 * </p>
 * <p>
 * By default, new buckets are created in the
 * {@link BucketVersioningConfiguration#OFF} state. Once versioning is enabled
 * for a bucket, its status can never be reverted to
 * {@link BucketVersioningConfiguration#OFF off}.
 * </p>
 * <p>
 * Objects created before versioning is enabled or while versioning is suspended
 * will be given the default <code>null</code> version ID (see
 * {@link Constants#NULL_VERSION_ID}). Note that the <code>null</code> version
 * ID is a valid version ID and is not the same as having no version ID.
 * </p>
 * <p>
 * The versioning configuration of a bucket has different implications for each
 * operation performed on that bucket or for objects within that bucket. When
 * versioning is enabled, a <code>PutObject</code> operation creates a unique
 * object version ID for the object being uploaded. The <code>PutObject</code>
 * operation guarantees that if versioning is enabled for a bucket at the time
 * of the request, the new object can only be permanently deleted by calling the
 * <code>DeleteVersion</code> operation and can never be overwritten.
 * </p>
 * <p>
 * Additionally, the <code>PutObject</code> operation guarantees that if
 * versioning is enabled for a bucket at the time of the request, no other
 * object will be overwritten by that request. Refer to the documentation
 * sections for individual APIs for information on how versioning status affects
 * the semantics of that particular API.
 * </p>
 * <p>
 * Amazon S3 is eventually consistent. It may take time for the versioning
 * status of a bucket to be propagated throughout the system.
 * </p>
