Add support for setting hashed passwords
This change will add support for hashed passwords in cc_set_passwords.
It checks if a password is a hash with by checking that it matches
in fairly safe way, and also that the password does not have a ":" in it.
chpasswd needs to know if the password is hashed or not, so two lists
is created so chpasswd is feed with the correct one.
