> HDDS-7230 implements the GetKeyInfo with the ability to assume S3 volume
> context by OM. That releases S3G from having to call `getS3VolumeContext`
> prior to calling `lookupKey`, as it does today.
> Changes include:
> - S3G Get Key API to call GetKeyInfo via RpcClient with
> `assumeS3Context=true` ( and without a `volumeName`). S3G doesn't need to
> call GetS3VolumeContext prior to GetKeyInfo.
> - RpcClient once it sees an S3 context in the GetKeyInfo response, takes the
> user principal, and sets it to the
> [S3LocalAuthContext|https://github.com/apache/ozone/blob/master/hadoop-ozone/client/src/main/java/org/apache/hadoop/ozone/client/protocol/ClientProtocol.java#L923-L923].
>
> That will reduce once roundtrip between S3G and OM for every GetKey API
> request.
