* Add gRPC SelectGroup and SelectProfile service endpoints * HTTP and gRPC servers should both allow labels to be resolved to the matching Group or Profile. Move logic to bootcfg core server. * Add gRPC wrapper selectServer to avoid cluttering core server with response types which are currently only useful for gRPC
