Review Comment:
   Maybe you can also put this under `hadoop-ozone/tools` too, so people can use the tool like Freon to experiment GRPC protocol.

Review Comment:
   So, do we need to make [the actual change](https://github.com/apache/ozone/blob/master/hadoop-ozone/common/src/main/java/org/apache/hadoop/ozone/om/OMConfigKeys.java#L341-L341) to make `GrpcOmTransportFactory` the default value for `ozone.om.transport.class`.
