Azure Stack operator experience feature updates

[Azure Stack operators](https://docs.microsoft.com/en-us/azure/azure-stack/azure-stack-key-features) can configure Azure Stack and manage offers, plans, services, quotas, and pricing to provide resources for their users. Azure Stack operators also manage capacity and can respond to alerts. We're developing new and updated features for the monitoring, diagnostics, and servicing experiences to ensure Azure Stack operators can keep the Azure Stack integrated system running and healthy. These include: * Investments in infrastructure servicing to minimize tenant downtime. * Improved alerting and remediations to allow the operator to maintain system health. * Updated diagnostics for better troubleshooting. * Continued investments in the Operator UX and Operator PowerShell.
