Marcelo Moreira de Mello 19932bce53 Introducing support to Melnor RainCloud sprinkler systems (#9287)
*  Introducing support to Melnor RainCloud sprinkler systems

* Make monitored_conditions optional for sub-components

*  Part 1/2 - Modified attributes, added DATA_ constant and using battery helper

* Part 2/2 - Refactored self-update hub

* Fixed change requested:
- Dispatcher signal connection
- Don't send raincloud object via dispatcher_send()
- Honoring the dynamic scan_interval value on track_time_interval()

* Inherents async_added_to_hass() on all device classes

* Makes lint happy

* * Refactored RainCloud code to incorporate suggestions.
  Many thanks to @pvizelli and @martinhjelmare!!

* Removed Entity from RainCloud sensor and fixed docstrings

* Update raincloud.py

* Update raincloud.py

* fix lint
