URL: https://github.com/apache/ozone/pull/10910
## What changes were proposed in this pull request?
gRPC 1.81.0 adds an info-level message that appears on console for shell
commands that involve Ratis:
```
$ mvn -Pdist -DskipRecon -DskipShade -DskipTests clean verify \
-Dratis.thirdparty.version=1.1.0 \
-Dratis-thirdparty.grpc.version=1.82.1 \
-Dratis-thirdparty.netty.version=4.1.136.Final \
-Dratis-thirdparty.protobuf.version=3.25.9
...
$ cd hadoop-ozone/dist/target/ozone-2.3.0-SNAPSHOT/compose/ozone
$ OZONE_DATANODES=3 ./run.sh -d
$ docker compose exec scm bash
$ ozone freon ockg -n1 -t1
...
$ ozone sh key put /vol1/bucket1/passwd /etc/passwd

loadEpollInfo
INFO: Epoll available during static init of TcpMetrics:true
```
Shell commands disable log4j logs by default. We should also suppress
messages from `java.util.logging`.
https://issues.apache.org/jira/browse/HDDS-16031
## How was this patch tested?
Same as above. `ozone sh key put` now suppresses `TcpMetrics` log.
