user-defined allow-list of devices in chart

[ruzko]

Hiya, thanks for making this very convenient device plugin!

I've used the container in my cluster for almost a year now (Home Assistant / Zigbee radio and prind / 3D printer), and I'm excited to see you've published a chart for it 👍

I don't know exactly what capabilities are given to containers running in a privileged context (like generic-device-plugin), so restraint might be useless. With this caveat, the way the chart proxies lots of host devices, without giving the user the option to choose themselves which paths to proxy, feels a bit overzealous (?). ref:

generic-device-plugin/charts/generic-device-plugin/templates/daemonset.yaml

Could we get a variable in the chart where we can define which paths to proxy, optionally overriding the defaults?

Again, cheers and much appreciated 🙂
