Entities prefix

[turbulator]

Oficial HA manual requeres next format of entity id: sensor.id_nickname. It isn't very useful because different groups of entities are mixing in list. Sometimes it takes a lot of time to find the right one. At my opinion much better to have format with prefix like this: sensor.prefix_id_nickname. Also I have found a lot of examples of this format in the repo. So, why not make optional boolean add_domain_prefix parameter in the config?

The final format will be like this: sensor.[pandora_cas_]1234567_engine_temperature
