Show some more information about the guest system

### Description

I was looking at adding some more basic details from the guest

This was available in the "host" structure, and in /etc/os-release.

I opened another issue, about the more dynamic information:

* Issue #835

This issue would be the more static part such as OS and total.

Similar to the output of "screenfetch" or "neofetch", but less clutter.

It is available through shell commands, but could use some JSON ?

Example info:
* OS
* Kernel

Some of these shell scripts are quite long...

And there seems to be some bugs, as well.
