ADR: platform-mesh/architecture#30

[gman0]

Current approach is to run the ManagedProvider reconciler as part of the main platform-mesh-operator Deployment. The Provider reconciler (kcp-facing, watching providers.platform-mesh.io APIExport VW) runs in a separate Deployment. Needs changes in the helm chart too.
