Azure Event Hub scaler doesn't log anything if the blob container name is wrong

[jrehnen]

While querying the scaling metric, if the scaler for Azure Event Hub cannot find the blob storage container the error message never gets logged.
Instead, the total amount of events in the hub is used as the value for the metric, whether they have already been handled or not.

This is due to the codeblock starting from the line in this link:

keda/pkg/scalers/azure_eventhub_scaler.go

Line 168 in 7b98173

checkpoint, err = azure.GetCheckpointFromBlobStorage(ctx, scaler.httpClient, scaler.metadata.eventHubInfo, partitionInfo.PartitionID)

Due to this it is currently incredibly difficult to locate an error caused by a wrong blob storage container name.
