Public preview: Azure Chaos Studio Key Vault and Classic Cloud Services faults

Azure Chaos Studio now has faults available for Azure Key Vault and Classic Cloud Services. The Key Vault Deny Access fault blocks all network access to a Key Vault by temporarily modifying the Key Vault network rules, preventing an application dependent on the Key Vault from accessing secrets, keys and/or certificates. The Classic Cloud Services Shutdown fault stops a deployment, simulating a service failure. Fault details are available in [the fault library](https://aka.ms/chaosstudiofaultlibrary) and these faults can be used in experiments created via Azure Resource Manager template or REST API. Adding these faults to an experiment using the experiment designer in the Azure portal will be available in the coming weeks. * Azure Chaos Studio * Key Vault * Cloud Services * Features * Management * [ Azure Chaos Studio](https://azure.microsoft.com/en-gb/products/chaos-studio/) * [ Cloud Services](https://azure.microsoft.com/en-gb/products/cloud-services/) * [ Key Vault](https://azure.microsoft.com/en-gb/products/key-vault/)
