This pr must be halt since we'll have issue if we use azapi_update_resource to manage additional ports, if we have secret defined in azurerm resource and we don't include them in azapi_update_resource, API would return error, complaining that we have passed incorrect values to secrets.

I'll open some pull requests to azurerm provider to bump API version, then bring these arguments into the resource schema.
