[Feature] Disable exposing groups
Please use the template and fill in all the data requested below!

**Problem description**
Since exposing groups by default, people using IKEA's old firmware for buttons are experiencing all bulbs, blinds, etc exposed twice.

In the latest firmware for IKEA buttons, they have removed group cast. The old way of controlling lights, was to add bulbs to an group and then bind the button to the group. That way you avoided the infamous "popcorn effect".

The downside of this nice feature, was that even if you would control just one bulb, it has to be in an group. This way you end up with the bulb itself and also an group for that same one bulb.

It could be fixed just by updating the firmware, but that would kill this nice feature the firmware have.

The good thing about the old firmware is that the group cast don't need the controller to be online to function, so even if the controller crash, you can still control all your light, blinds, etc.

**Suggested solution**
Disable exposing groups by default, and be able to expose them by their group id instead of the friendly name (friendly name accept spaces and non English letters)

**Describe alternatives you've considered**
Downgrading to an release prior to group exposure was default.
