Review Comment:
I think one risk here is that it is now possible to create a cluster with
all empty cluster urls. I think it might make sense to verify that there is
some URL that is not zero length.
Additionally, one benefit of this change is for clusters that only want to
supply a TLS url.
What is your opinion @nodece?
