Expected results:
a, root login allowed with same key as tripleo-admin.
Using sunder user usually recommended because of auditing reason,
Regardless to using tripleo-admin or root the actual human cannot be known better.
b, print an existing no password sudoer user, like tripleo-admin instead of 'NONE',
c, Rephrase the sentence to do not look like somebody forget some template variable somewhere.
