Reserve 1% of disk space by default

Many people are not aware that Kudu is able to reserve a certain amount
of space per disk for non-Kudu usage and they don't set the
corresponding flags. Let's bump the default from 0 to a special value
indicating one percent, which seems like a reasonable default in most
cases.
