Fundamentally, this component is responsible for the following:

- Sets up redirection with newly-started (or newly-added, previously-started) application pods such that traffic from application pods is forwarded to the local node's ztunnel pod.
- Configures required iptables, sockets, and packet routing miscellanea within the `ztunnel` and application pod network namespaces to make that happen.

This component accomplishes that in the following ways:

  // which corresponds to the IfHealthyBudget policy.
  //
  // IfHealthyBudget policy means that running pods (status.phase="Running"),
  // but not yet healthy can be evicted only if the guarded application is not
  // disrupted (status.currentHealthy is at least equal to status.desiredHealthy).
  // Healthy pods will be subject to the PDB for eviction.
