[BUG] 1 hour lag on Azure storage metric (UsedCapacity)

[haedri]

What is the module?
azure-storage-account

What is the detector?
Azure Storage Account count
Azure Storage Account capacity

Describe the bug
There's a one hour lag on UsedCapacity because the metric is sent late by Azure according to Splunk support :

These metrics look to be published hourly by Azure, which explains the hourly lag. Azure Blob Storage monitoring data reference - Azure Storage

So the detector can not trigger (max delay is 15 minutes)
Support says we should use timeshift method to add a one hour timeshift, and this seems to fix the problem indeed
