should we name this role "RemoteDatastorePowerUser", to match the local role?

and this would then become RemoteDatastoreAdmin ? although that is not a 1:1
match, since DatastoreAdmin also includes verify, read, ..

naming the roles just after the privs might bite us down the line, if we ever
extend/split the privs..
