What happened?
I see that oci-flexvolume-driver is logging like this:
2020-12-31T16:18:58.739Z INFO metadata/instance_metadata.go:87 Metadata endpoint /opc/v2/instance/ returned response successfully

Notice the empty lines. I think these empty lines shouldn't be there. They are then incorrectly tracked by our logging system as a separate event.
What you expected to happen?
I expect it to be like this instead:
2020-12-31T16:18:58.739Z INFO metadata/instance_metadata.go:87 Metadata endpoint /opc/v2/instance/ returned response successfully
2020-12-31T16:18:58.739Z INFO client/utils.go:94 OCI using read rate limit configuration: QPS=20, bucket=5 {"pid": 26564, "version": "", "build": "", "command": "init"}

How to reproduce it (as minimally and precisely as possible)?
I think this is the standard behavior of oci-flexvolume-driver on any environment, so it should be easy to reproduce
