Azure: Add Storage Accounts file detectors

[BzSpi]

Relates to #206

I've made the following remarks to splunk regarding their implementation:

I took a look at the metrics and found some implementaion that does not fit well

• The file share name dimension is sometimes named "FileShare" (metrics Transactions, Egress, Ingress) and sometimes "fileshare" (metrics FileCapacity, FileShareCapacityQuota, FileShareSnapshotCount...). Comparing the metrics is only possible by doing dimensions renaming in signlaflow
• The storage account tags dimensions are missing for some metrics (FileShareCapacityQuota, FileShareSnapshotCount...)
• The dimension azure_resource_name is missing on some metrics

We achieved to have workarounds for "file share" dimension casing and lack of azure_resource_name dimensions prevent using the metrics in production.

Set the non working detectors (those without filtering) to disabled by default.
