- 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:

  // TopologyKey is the key of node labels. Nodes that have a label with this key
  // and identical values are considered to be in the same topology.
  // We consider each <key, value> as a "bucket", and try to put balanced number
  // of pods into each bucket.
  // We define a domain as a particular instance of a topology.
  // Also, we define an eligible domain as a domain whose nodes meet the requirements of
