Creates or updates a virtual network link to the specified Private DNS zone.

 @param resource_group_name [String] The name of the resource group.
 @param private_zone_name [String] The name of the Private DNS zone (without a
 terminating dot).
 @param virtual_network_link_name [String] The name of the virtual network
 link.
 @param parameters [VirtualNetworkLink] Parameters supplied to the
 CreateOrUpdate operation.
 @param if_match [String] The ETag of the virtual network link to the Private
 DNS zone. Omit this value to always overwrite the current virtual network
 link. Specify the last-seen ETag value to prevent accidentally overwriting
 any concurrent changes.
 @param if_none_match [String] Set to '*' to allow a new virtual network link
 to the Private DNS zone to be created, but to prevent updating an existing
 link. Other values will be ignored.
 @param custom_headers [Hash{String => String}] A hash of custom headers that
 will be added to the HTTP request.

 @return [VirtualNetworkLink] operation results.
