Briefly describe the feature

Add "Reboot required" field in Homepage integration

Detailed description

The current Homepage integration includes a number of useful fields, but I think one that is missing is the "Reboot required" field.

Why is this useful?

It would be nice to know via widget that one or more hosts need a reboot after patching, especially once scheduled patching is implemented.
