Review comment:
By the way @stijndehaes I haven't been able to find the document that
says the max name length of any configmap is 63 char long. From my quick
command line test, I found it can be well over beyond that number. Could you
confirm this limit is needed. Well, I do agree it is always good to be
defensive but I found there is no such shortening logic for driver configmap
either. So, could you confirm? Thanks.
