[Feature]: add a configurable grace period for Windows Defender antivirus patterns

What is the installation method of your PatchMon server?

Proxmox-community script

What is the version of your PatchMon server?

2.0.2

Briefly describe the feature

Allow a "x" days threshold to be set for windows defender patterns until they are deemed out of date

Detailed description

Test lab with @50-odd windows machines, constant lag on patchmon's knowledge of available defender pattern updates vs client checkin to WSUS and deployment. This is no way a bug, its simply defender being updated several times a day.

I think it would be useful to allow a selectable setting of 0-7 days grace period before defender deemed out of date, this would stop the lag as above whilst retaining patch knowledge, the flag could be set globablly, overriden per-group or per-individual-client.

Hope this makes sense, close if not appropriate and thank you for Patchmon!

Why is this useful?

Enable a little flexibility before reporting defender signatures as out-of-date
