## IstioOperatorSpec API

The `IstioOperatorSpec` API is intended to replace the installation and K8s parts of Helm values.yaml.

### Features and components

The operator has a very similar structure to istio/installer: components are grouped into features.
`IstioOperatorSpec` defines functional settings at the feature level. Functional settings are those that performs some

  // implementation will use to handle pods of this class. The possible values
  // are specific to the node & CRI configuration.  It is assumed that all
  // handlers are available on every node, and handlers of the same name are
  // equivalent on every node.
  // For example, a handler called "runc" might specify that the runc OCI
  // runtime (using native Linux containers) will be used to run the containers
  // in a pod.
