Support for Nuki.io smart locks (#5715)

* Support for Nuki.io smart locks

* Update requirements and add lock.nuki to .coveragerc

* lint: Re-organize imports

* Schedule a state update instead of calling directly update_ha_state

* Remove update requests altogether

* Make sure there is no IO inside properties

* Fix: nuki lock are all initialized as "lock.unnamed_device"

* Update pynuki to 1.2 to avoid an extra REST API call for each lock init
