exclude device from automatic backup

[no-Legend]

I'm running a lot of different devices with Tasmota.
Also there are a few devices running which are with a self compiled firmware.
For example especially with SML support.

If I'm now going to update the device by Tasmota admin I need to select every device I want to update with a click.
Also I need to be aware not to update the device with the sleve compiled firmware.

What should we implement

Instead to select all the device I can update it would be better to set in the device setting that this special device is not updateable.
In other words in the settings where also the name is seated there is checkbox which will be activated to exclude this device from the auto update function
So I did not net to care about this devices all the time.

Cheers Robert

Isn't this the same as the "is updatable" option?

This was implemented in #944
