Complex logic ahead...
We have three sets of values, in order of precedence (last wins):
1. The builtin values.yaml defaults
2. The profile the user selects
3. Users input (-f or --set)

Unfortunately, Helm provides us (1) and (3) together (as .Values), making it hard to insert (2).

However, we can workaround this by placing all of (1) under a specific key (.Values.defaults).

Helm charts Istio historically offered two different charts - `manifests/charts/gateways/istio-ingress` and `manifests/charts/gateways/istio-egress`. These are replaced by this chart. While not required, it is recommended all new users use this chart, and existing users migrate when possible. This chart has the following benefits and differences: * Designed with Helm best practices in mind (standardized values options, values schema, values are not all nested under `gateways.istio-ingressgateway.*`,...

### Advanced K8s resource overlays

Advanced users may occasionally have the need to customize parameters (like container command line flags) which are not
exposed through either of the installation or configuration APIs described in this document. For such cases, it's

  // controller. If a Job is suspended after creation (i.e. the flag goes from
  // false to true), the Job controller will delete all active Pods associated
  // with this Job. Users must design their workload to gracefully handle this.
  // Suspending a Job will reset the StartTime field of the Job, effectively
  // resetting the ActiveDeadlineSeconds timer too. Defaults to false.
