Overhaul of Blink platform (#16942)

* Using new methods for blink camera

- Refactored blink platform (breaking change)
- Camera needs to be uniquely enabled in config from now on
- Added motion detection enable/disable to camera platform

* Fix motion detection

- bumped blinkpy to 0.8.1
- Added wifi strength sensor

* Added platform schema to sensor

- Added global variables for brand and attribution to main platform

* Removed blink binary sensor

* Add alarm control panel

* Fixed dependency, added alarm_home

* Update requirements

* Fix lint errors

* Updated throttle times

* Add trigger_camera service (replaced snap_picture)

* Add refresh after camera trigger

* Update blinkpy version

* Wait for valid camera response before returning image

- Motion detection now working!

* Updated for new blinkpy 0.9.0

* Add refresh control and other fixes for new blinkpy release

* Add save video service

* Pushing to force bot to update

* Changed based on first review

- Pass blink as BLINK_DATA instead of DOMAIN
- Remove alarm_arm_home from alarm_control_panel
- Re-add discovery with schema for sensors/binar_sensors
- Change motion_detected to a binary_sensor
- Added camera_armed binary sensor
- Update camera device_state_attributes rather than state_attributes

* Moved blink.py to own folder. Added service hints.

* Updated coveragerc to reflect previous change

* Register services with DOMAIN

- Change device add for loop order in binary_sensor

* Fix lint error

* services.async_register -> services.register
