$ID/$AUTH provision urls, regression

Created by: bjoto

In commit 7514d930 ("rework stboot configuration") a regression is introduced; ID/AUTH is not replaced in the provisioning URL.

Further, the hostconfiguration printout is misspelled (Security and not Host) and weird:

[DEBUG] stboot: Security configuration: {
