In our testing, even the most generous representations give custom types a 10x edge (in size, allocations, and CPU time) over Envoy types.
In addition, they are more clear and strictly typed; using Envoy types would require us to put a lot of information in untyped `metadata` maps.

With this in mind, Ztunnel supports two xDS resources: `Address` and `Authorization`.

### Address Type

#### Mesh Config

Mesh Config controller is a pretty simple controller, reading from `ConfigMap`(s) (multiple if `SHARED_MESH_CONFIG` is used), processing and merging these into a the typed `MeshConfig`. It then exposes this over a simple `mesh.Watcher`, which just exposes a way to access the current `MeshConfig` and get notified when it changes.

            than specifying a value for finalName directly in the plugin configuration section. It is also useful to
            ensure that - for example - a List-typed parameter which expects items of type Artifact doesn't get a List
            full of Strings.
