/**
 * Configuration settings for storing attachments in Azure Blob Storage as part of the remote attachments feature.
 *
 * This class configures the remote storage destination for attachments using Microsoft Azure Blob Storage.
 * Remote attachments allow offloading large attachment files from the local RavenDB database to cloud storage,
 * helping to reduce database size and improve performance for scenarios with many or large attachments.
 *
 * Azure authentication can be configured using either:
 * - Account Key: Using accountName and accountKey
 * - Shared Access Signature (SAS): Using accountName and sasToken
