> 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.
