If the Docker startup script is passed both "--alternator-port" and "--alternator-https-port", a combination which is supposed to be allowed, it passes to Scylla the "--alternator-address" option twice. This isn't necessary, and worse - not allowed. So this patch fixes the scyllasetup.py script to only pass this parameter once. Fixes #10016.
