### CmdAdd Sidecar Workflow

`CmdAdd` is triggered when there is a new pod created. This runs on the node, in a chain of CNI plugins - Istio is
run after the main CNI sets up the pod IP and networking.

1. Check k8s pod namespace against exclusion list (plugin config)

  // as having been marked for deletion (or after a timeout). The key in the map is the name of the pod
  // and the value is the time when the API server processed the eviction request. If
  // the deletion didn't occur and a pod is still there it will be removed from
  // the list automatically by PodDisruptionBudget controller after some time.

  // Requests with the dryRun attribute will be auto-rejected if they match a webhook with
  // sideEffects == Unknown or Some.
  optional string sideEffects = 6;

  // TimeoutSeconds specifies the timeout for this webhook. After the timeout passes,
  // the webhook call will be ignored or the API call will fail based on the
  // failure policy.
  // The timeout value must be between 1 and 30 seconds.
  // Default to 10 seconds.
  // +optional

  // ttlSecondsAfterFinished after the Job finishes, it is eligible to be
  // automatically deleted. When the Job is being deleted, its lifecycle
  // guarantees (e.g. finalizers) will be honored. If this field is unset,
  // the Job won't be automatically deleted. If this field is set to zero,
  // the Job becomes eligible to be deleted immediately after it finishes.
  // +optional

## Proxy implementation

In its initial implementations, the ztunnel was actually implemented in 3 different ways: a bespoke Rust implementation, a bespoke Go implementation, and in Envoy.

In the end, [after evaluation](https://docs.google.com/document/d/1c2123cKuYsBDpIon9FFdctWTUIMFweSjgwG7r8l3818/edit), the decision was to move forward with a Rust implementation.

  // addressType specifies the type of address carried by this EndpointSlice.
  // All addresses in this slice must be the same type. This field is
  // immutable after creation. The following address types are currently
  // supported:
  // * IPv4: Represents an IPv4 Address.
  // * IPv6: Represents an IPv6 Address.
  // * FQDN: Represents a Fully Qualified Domain Name.

  //   },
  //   ...
  // }
  //
  // Note: Audience in each TokenRequest should be different and at
  // most one token is empty string. To receive a new token after expiry,
  // RequiresRepublish can be used to trigger NodePublishVolume periodically.
  //
  // +optional
  // +listType=atomic
  repeated TokenRequest tokenRequests = 6;

// In the example: http://<host>/<path>?<searchpart> -> backend where
// where parts of the url correspond to RFC 3986, this resource will be used
// to match against everything after the last '/' and before the first '?'
// or '#'.
message HTTPIngressRuleValue {
  // paths is a collection of paths that map requests to backends.
  // +listType=atomic
  repeated HTTPIngressPath paths = 1;
