> Implement the S3 {{GetBucketObjectLockConfiguration}} operation to allow users to retrieve the Object Lock status and default retention settings of a bucket. This task covers S3 Gateway REST routing, OM authorization, and {{BucketTable}} read resolution.
> {*}1. S3 Gateway ({{{}hadoop-ozone/s3gateway{}}}){*}:
>  * Add route handler for {{{}GET /\{bucket}?object-lock{}}}.
>  * Forward the request to Ozone Manager via client protocol.
>  * Serialize the returned configuration into the standard S3 {{ObjectLockConfiguration}} XML response:
>  ** {{<ObjectLockEnabled>Enabled</ObjectLockEnabled>}}
>  ** Optional {{<Rule><DefaultRetention><Mode>...</Mode><Days>...</Days></DefaultRetention></Rule>}}
>  * Map OM exceptions to standard S3 error responses:
>  ** Return {{404 NoSuchBucket}} if the target bucket does not exist.
>  ** Return {{404 ObjectLockConfigurationNotFoundError}} ({{{}The specified object does not have a ObjectLock configuration{}}}) if the bucket exists but {{objectLockEnabled}} is {{{}false{}}}.
> {*}2. Protobuf Protocol ({{{}OmClientProtocol.proto{}}}) & OM Client{*}:
>  * Add RPC messages:
>  ** {{GetBucketObjectLockConfigRequest}} (contains {{{}volumeName{}}}, {{{}bucketName{}}}).
>  ** {{GetBucketObjectLockConfigResponse}} (contains {{objectLockEnabled}} and optional {{{}defaultRetention{}}}).
>  * Register request in {{OmClientProtocol}} and wire through {{{}OzoneManagerProtocolClientSideTranslatorPB{}}}.
> {*}3. OM Read Path / Metadata Handler ({{{}hadoop-ozone/ozone-manager{}}}){*}:
>  * Authorize the incoming request against Ranger action {{GetBucketObjectLockConfiguration}} (requiring bucket {{READ}} permission).
>  * Acquire bucket read lock and lookup target bucket in {{{}BucketTable{}}}.
>  * If bucket does not exist, throw {{{}BUCKET_NOT_FOUND{}}}.
>  * Check if object lock is enable.
