---------------------------------------------------------------------
We should have a generic metrics2 adapter for rocksdb metrics that can be used
in SCM, OM and Datanodes.
Additionally, a Datanode will have multiple instances of rocksdb one for each
container, it should be possible to prefix the metrics with container-id.
Please also note that DN will have thousands of containers and hence thousands
of rocksdb instances, so we might have scale concerns as well. We should
consider datanode rocksdb metrics in a separate jira.
