Support Firewall inventory

The GLPI agent is capable of collecting and sending information about the active firewalls on the computer; however, GLPI does not make use of this data. It would be nice if this information were reflected in the computer asset.

Example:

Windows:

"firewalls": [
{
"profile": "DomainProfile",
"status": "on"
},
{
"profile": "PublicProfile",
"status": "on"
},
{
"profile": "StandardProfile",
"status": "on"
}
],

Linux:

"firewalls": [
{
"description": "ufw",
"status": "on"
}
