feat: configure secondary ips for NFS protocol

[kristina-solovyova]

Contains only NFS part from PR #204

NFS settings in main.tf:

module "weka_deployment" {
  ...
  nfs_setup_protocol = true
  nfs_protocol_gateways_number = 3
  nfs_protocol_gateway_secondary_ips_per_nic = 3
  nfs_protocol_gateway_fe_cores_num = 1
}

Result - secondary IPs are listed and NSF setup is complete:

weka nfs interface-group --json
