Enhance system.sw.packages to auto-add template to an host with auto-registering

Hi,

Currently auto-register only use metadata field limited to 255 char to filter hosts.

This is usefull to filter between windows and linux but very limited if you want more automation.

Auto-register working with agent active, I would be nice to have another field that use system.sw.packages to auto add template to hosts. Currently theres no easy and automated way to add template to host

The process could be something like :

Host register to server => Server detect windows/linux metadata and filter on that (if auto discover rule is set) => Server filter on system.sw.packages and add template to hosts (with rules added in autoregister action).

Regards
