When fetching certificates, ztunnel will authenticate to the CA with its own identity, but request the identity of another workload.
Critically, the CA must enforce that the ztunnel has permission to request that identity.
Requests for identities not running on the node are rejected.
This is critical to ensure that a compromised node does not compromise the entire mesh.

## Installing

The new installer is intended to be modular and very explicit about what is installed. It has
far more steps than the Istio installer - but each step is smaller and focused on a specific
feature, and can be performed by different people/teams at different times.

It is strongly recommended that different namespaces are used, with different service accounts.

    * Behavioral changes should be highly scrutinized, while typo fixes don't require that level of scrutiny.
* It is preferable that cherry-picks are done by the istio-testing bot.
    * Automated cherry-picks do not need subject-matter experts to approve if discussed in the original PR.
* All changes should have an associated GitHub issue and/or a release note.

  // scope specifies the scope of this rule.

  // "Cluster" means that only cluster-scoped resources will match this rule.
  // Namespace API objects are cluster-scoped.
  // "Namespaced" means that only namespaced resources will match this rule.
  // "*" means that there are no scope restrictions.
  // Subresources match the scope of their parent resource.
  // Default is "*".

  // "Queue" means that requests that can not be executed upon arrival
  // are held in a queue until they can be executed or a queuing limit
