## What changes were proposed in this pull request?
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 proper `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 code change reduces once roundtrip between S3G and OM for every S3
Object Get/Head request.
