> Issue Type: Improvement

> Fix For: 1.2.0
>
>
> Currently, OmKeyInfo uses a `keyLocationVersions:
> List<OmKeyLocationInfoGroup>` to store all versions of KeyLocation
> information. If a key has lots of versions, OM needs to reply all the content
> of `keyLocationVersions` to the client, which may cause the following IPC
> warning, when the size exceeds the client IPC response size limit becomes an
> error.
> {code:java}
> 2021-05-18 23:10:07,246 [IPC Server handler 97 on default port 9862] WARN
> org.apache.hadoop.ipc.Server: Large response size 20541123 for call Call#3
> Retry#0
> org.apache.hadoop.ozone.om.protocol.OzoneManagerProtocol.submitRequest from
> 10.130.20.239:46306
> {code}
> This ticket is to add an config for client to only query the latest content
> in `keyLocationVersions`, which can reduce the IPC response size and improve
> OM's performance by excluding lots of unnecessary work with old key locations.
