Spike in EFS client connections after upgrading from version 1.7.7 to version 2.0.6

[gurskyi277]

We noticed that after updating the add-on of aws-efs-csi-driver from version 1.77 to version 2.0.6 on our EKS cluster, there was an increase in client connections to the EFS, which is simultaneously mounted to several of our services running in EKS.

In version 1.7.7, there were 2 client connections regardless of the number of pods using EFS. After upgrading to version 2.0.6, the number of connections increased, proportional to the number of pods using EFS multiplied by 2.

This is not an issue, but we would like to understand if this is the correct behavior after the driver update, or if it might be a misconfiguration on our part.
