fix(alternator): create a role with "login" and "superuser" flags

since scylladb/scylladb#19740 was recently merge, we need to
put the `login=true` for using roles with alternator

and when scylladb/scylladb#19762 would be merged
we'll need the `superuesr=true`, or do fine grind premission
for any action we need
