  // For example, if deployments can be modified via apps/v1 and apps/v1beta1, and a webhook registered a rule of
  // `apiGroups:["apps"], apiVersions:["v1"], resources: ["deployments"]` and `matchPolicy: Equivalent`,
  // an API request to apps/v1beta1 deployments would be converted and sent to the webhook
  // with `kind: {group:"apps", version:"v1", kind:"Deployment"}` (matching the rule the webhook registered for),

stable version in place and gradually migrate apps to the new version.

- More flexibility: the new installer allows multiple 'environments', allowing applications to select
a set of control plane settings and components. While the entire mesh respects the same APIs and config,
apps may target different 'environments' which contain different instances and variants of Istio.
