Error when creating rancher2_machine_config_v2 using Azure

[02bensch]

Problem:
When using rancher2_cluster_v2 with rke_config that references a rancher2_machine_config_v2 using azure_config an error occurs, also when using an empty machine config.

Error:
Error: Invalid address to set: []string{"azure_config", "0", "private_address_only"}

Adding the parameter private_address_only also gives an error, because the parameter is not expected in the rancher2_machine_config_v2 azure_config nested block.
