> Currently, app attempt ClientToken master key is registered before it is
> saved. This can cause problem that before the master key is saved, client
> gets the token and RM also crashes, RM cannot reloads the master key back
> after it restarts as it is not saved. As a result, client is holding an
> invalid token.
> We can register the client token master key after it is saved in the store.
