resmgr: move/generate resmgr API/types to pkg/apis.
Move resmgr API and types to pkg/apis/resmgr/v1alpha1, next to other generated APIs (currently config). This allows annotating the types for better CRD validation which is useful if we use them in our config CRDs. Annotate Expression operator for better validation.
