Rename some createuser options.

This change renames --admin to --with-admin, --role to --member-of,
and --member to --with-member.  Many people found the previous
names to be confusing.  The --admin and --member options are new in
v16, but --role has been there for a while, so that one has been
kept (but left undocumented) for backward compatibility.
