#### 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.
