Renewal fails when App Service Plan and App Service reside in different resource groups

[ohadschn]

I believe the issue is here:

letsencrypt-azure/src/LetsEncrypt.Azure.Core.V2/CertificateConsumers/AzureWebAppService.cs

Line 73 in bafb426

await appServiceManager.Inner.WebApps.CreateOrUpdateHostNameBindingAsync(setting.ServicePlanResourceGroupName ?? setting.ResourceGroupName, setting.WebAppName, hostName, binding);

While the certificate should indeed be created in the App Service Plan resource group (found that out the hard way), the binding should use the App Service's resource group (so setting.ServicePlanResourceGroupName should be ignored in this line even if specified).

The error looks like this:

Microsoft.Rest.Azure.CloudException: Can not perform requested operation on nested resource. Parent resource 'my-web-app' not found.
