[virt-tools-list] [virt-manager PATCH 2/2] unattended: Don't log user & admin passwords

Logging user & admin passwords in the command-line is a security issue,
let's avoid doing so by:
- Not printing the values set by the user when setting up the
install-script config file;
- Removing the values used in the install-scripts, when printing their
content;

'CVE-2019-10183' has been assigned to the virt-install --unattended
admin-password=xxx disclosure issue.
