​AFAIK upgrade part of host-deploy in 4.1 and below just upgraded specific
packages, nothing else.

PKI stuff is handled by installation part of host-deploy, which can be
execute by clicking Reinstall on existing hosts.

There was/is a slight confusion between these 2 parts​:

1. Upgrade
    - always perform only upgrade of packages: in 4.1 and below only
specific ones, in 4.2+ all packages with ability to reboot a host after
upgrade

2. Reinstall
    - it perform exactly the same steps as Installation: performing
configuration, install/updating required packages, enrolling certiifcation,
executing setup networks ...
