Monitor expiration events from Azure Key Vault

Microsoft's Azure Key Vault helps customers safeguard sensitive keys and secrets used by applications and services hosted on Azure. However, it can be challenging to determine when resources in the Key Vault are about to expire. Datadog Azure Key Vault Integration now generates out-of-the-box expiration events that alert users when credentials or secrets stored in the Key Vault are about to expire. These alerts give advance notice so users can renew soon-expiring keys before they are no longer usable, preventing disruptions and saving time and money. The Azure Key Vault integration also generates missing permission events when Datadog has not been granted access to an Azure Key Vault.
