BlobService check requires Storage Account Owner permissions

[richardjharding]

Make the call to Get Blob Service Properties optional - perhaps based on the Options object used in this check

As currently implemented this line

AspNetCore.Diagnostics.HealthChecks/src/HealthChecks.AzureStorage/AzureBlobStorageHealthCheck.cs

Line 44 in a508476

var serviceProperties = await blobServiceClient.GetPropertiesAsync(cancellationToken);

Seems to require a high level of authorisation - according to the ms docs it needs storage account owner role - https://docs.microsoft.com/en-us/rest/api/storageservices/get-blob-service-properties#authorization

In my case I was looking to limit the necessary permissions for my app to just those required to access the blob container but adding this health check means I need to grant excessive permissions (imho :))

We had the same problem when using the health checks in an enterprise context. The account used by our application does not have the storage account owner permission, but we would like to perform the health check.

Any idea when this will be merged, the PR looks good?
