* Ensure traffic between mesh workloads is securely encrypted with an Istio identity.
* Be lightweight enough to not limit adoption.
  * This puts a much tighter budget on CPU, memory, latency, and throughput requirements than traditional Istio sidecars.

Ztunnel was not designed to be a feature-rich data plane.

The details for the deployment & installation of this plugin were pretty much lifted directly from the
[Calico CNI plugin](https://github.com/projectcalico/cni-plugin).

Specifically:

  // This field is immutable.
  // +optional
  optional k8s.io.api.core.v1.NodeSelector nodeSelector = 1;

  // perNodeHostBits defines the number of host bits to be configured per node.
  // A subnet mask determines how much of the address is used for network bits
  // and host bits. For example an IPv4 address of 192.168.0.0/24, splits the
  // address into 24 bits for the network portion and 8 bits for the host portion.

  // encountered when an authorizer, such as an external authorizer, doesn't support rules evaluation.
  optional bool incomplete = 3;

  // EvaluationError can appear in combination with Rules. It indicates an error occurred during

1. First, the request is handled by the SDS server. This is mostly just an intermediate translation layer exposing
   the `SecretManager` to Envoy, without much business logic. For each resource requested by Envoy, the SDS server
   will call `SecretManager.GenerateSecret(resourceName)`
