[controller] Fix CSI NFS v3(tcp) support

[AleksZimin]

Description

This PR addresses issues with NFS v3 support in the CSI controller and node containers by introducing the following changes:

1. Socket mounting: Added mount of the /run/rpcbind.sock socket to both the CSI controller and CSI node containers.
2. Init Container: Added an init container that ensures the availability of the /run/rpcbind.sock socket before starting.
3. Distroless Image Enhancements: Included the /etc/netconfig file and the libnss_files library in the distroless image to enable CSI to mount NFS v3 over TCP.

Why do we need it, and what problem does it solve?

The changes ensure proper support for NFS v3 over TCP in CSI deployments. Without these adjustments, the CSI controller and node were unable to mount NFS v3 volumes due to missing libraries and socket forwarding issues.

What is the expected result?

• Successful mounting of NFS v3 volumes over TCP by the CSI controller and node.

Checklist

• The code is covered by unit tests.
• e2e tests passed.
• Documentation updated according to the changes.
• Changes were tested in the Kubernetes cluster manually.
