* vicare: add set_vicare_mode service
The set_vicare_mode service allows the user to set any of the possible heating
modes of their heating device. Not just the ones that were mapped to
home assistant climate modes.
* vicare: Undo async changes and add heating mode
Useless async changes were undone.
To be able to set the most relevant modes the set_vicare_mode
shall be able to also set the heating mode (without domestic
hot water)
* Extract kwarg and undo some more async changes
Currectly extract the service argument
Adapt according to review
* Lint fixes
* Replace kwargs with single arg
