Add warning line to update entities, warn for some Z-Wave OTA updates

[AlCalzone]

e.g. if the device requires being re-included after the update

In some cases a device can be updated but the update has consequences, like it needs be re-included. We do not want users to just update the device without telling them about the fallout. The users needs to do an additional confirmation and we want to show a warning.

• A user should see a special visual element that the update is major / has additional actions.
• When a user wants to update, the update entity should;
  • have an additional parameter in the service call
  • has a extra prompt in the UI

Design suggestion:

Add a parameter to the service call that allows such updates, otherwise raise an exception in the service call, and a state attribute to mark the entity as major/breaking? Frontend should be updated with confirmation dialog or similar.
