Commit 019a2e3a27 marked some arguments as required, which improved
the usability of scylla_setup.
The problem is that when we call scylla_setup in interactive mode,
no argument should be required. After the aforementioned commit
scylla_setup will either complain that the required arguments were
not passed if zero arguments are present, or skip interactive mode
if one of the mandatory ones is present.
This patch fixes that by checking whether or not we were invoked with
no command line arguments and lifting the requirements for mandatory
arguments in that case.
