[cinder-csi-plugin] implement structured logging

[sergelogvinov]

What this PR does / why we need it:

implement structured logging KEP 1602

CSI plugins often use common values like node name, volume name, volume ID, and instance ID in unstructured error and log messages. This makes it hard to group and sort them. I want to change these logs to structured logs, as the core Kubernetes team has decided to move in this direction

Current logs:

CreateVolume: Successfully created volume 47d323fd-b06c-424e-b27b-d27db2fb2c5c in Availability Zone: nova of size 10 GiB

Structured logs

"Successfully created volume" func="CreateVolume" volumeID="228d4464-48a2-4a45-81a7-24d3d0a1862a" size=10 zone="nova"
"Successfully detached volume" func="ControllerUnpublishVolume" volumeID="228d4464-48a2-4a45-81a7-24d3d0a1862a" instanceID="89e33913-0cce-4c1a-be2f-4e6a39d32b51"
"Successfully deleted volume" func="DeleteVolume" volumeID="228d4464-48a2-4a45-81a7-24d3d0a1862a" cloud=""

Default log keys:

• func- name of function, example CreateVolume
• size - volume size
• volume - volume name
• volumeID - volume ID
• snapshotID - snapshot ID
• instanceID - instance ID
• zone - availability zone
• cloud - cloud config

Which issue this PR fixes(if applicable):

make sense after #2640

Hi @sergelogvinov. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

Also its worth to add this link for the context https://github.com/kubernetes/enhancements/blob/master/keps/sig-instrumentation/1602-structured-logging/README.md#new-klog-methods
The release notes are must have for such changes.
