Introduced Ring binary sensors and refactored Ring component (#6520)

* - Introduced Ring binary_sensor.

- Added unittest for Ring binary_sensor.

- Bumped ring_doorbell 3rd party module.

* Updated requirements

* Added correct file for unittest

* - Introduced Ring binary_sensor.

- Added unittest for Ring binary_sensor.

- Bumped ring_doorbell 3rd party module.

* Updated requirements

* Added correct file for unittest

* Added extra sensors last_ding and last_motion

* Modified Ring binary_sensor and sensor to inherit DOMAIN configuration

* Moved static to top ring.py

* Fixed requirements

* Bump version ring_doorbell to 0.1.2

* testing unittests

* Use hass.data dict instead GLOBALS

* Fixed unittests

* Bump ring_doorbell to 0.1.3

* Updated unittest and coverted to use decorator @requests_mock.Mocker()

* Updated ring_session with lower case
