LGTM +1 (non binding), also I do not think the test failures are related. I
have seen those tests fail of late in all the PRs. I believe there are jiras
logged already to fix them.

Work Description: adoroszlai commented on pull request #1283: HDDS-1954.
StackOverflowError in OzoneClientInvocationHandler
URL: https://github.com/apache/hadoop/pull/1283
## What changes were proposed in this pull request?
Including `proxy` in the trace message causes stack overflow, since it
results in a call to `proxy.toString()`, which also wants to log, etc.
I would also argue that `target` is more interesting for logging than
`proxy`: eg. `org.apache.hadoop.ozone.client.rpc.RpcClient@5c3d4f05` vs.
`com.sun.proxy.$Proxy87`.
https://issues.apache.org/jira/browse/HDDS-1954
## How was this patch tested?
Set root log level to TRACE and ran some integration tests via Maven (eg.
`TestOzoneRpcClientWithRatis`). Verified that `surefire-reports` has no
`StackOverflowError`, but has messages like:
```
TRACE client.OzoneClient (OzoneClientInvocationHandler.java:invoke(51)) -
Invoking method public abstract org.apache.hadoop.ozone.client.OzoneVolume
org.apache.hadoop.ozone.client.protocol.ClientProtocol.getVolumeDetails(java.lang.String)
throws java.io.IOException on target
org.apache.hadoop.ozone.client.rpc.RpcClient@5c3d4f05
