### Install Control plane

This can run in any cluster. A mesh should have at least one cluster should run Pilot or equivalent XDS server,

			// or via the cni plugin. If it happens to get here before the cni plugin somehow,
			// then we will just fail to add the pod to the mesh, and it will be retried later when cni plugin adds it.

			// We need a pod IP - if the pod was added via the CNI plugin, that plugin told us the IPs
			// for the pod. If this is a pod added via informer, the pod should have already gone thru

* All traffic *ingressing* a pod on port 15008 in the mesh is assumed to be HBONE, and should be redirected to the node-local ztunnel on port 15008 (more on this later).
* All other traffic *ingressing* a pod in the mesh should be redirected to the node-local ztunnel on port 15006, regardless of intended original destination port.
