Tom 08524953bf Add Environment Variable Override (#4085) ...

* Add Environment Variable Override

I need to be able to manage settings on this service via Environment Variables.   I've added the ability to override anything in the settings schema with a corresponding environment variable.  

e.g. to override settings.serial.port you can set ZIGBEE2MQTT_SERIAL_PORT=/dev/ttyS0
to override the mqtt username you can set ZIGBEE2MQTT_MQTT_USER=testusername

This new addition will not perform any action on existing installations unless the matching environment variable is set.  I have tested this setting string, number, boolean, object and array values.

* Adding test case for environment variables and slight modification to ensure 100% code coverage.

* Adding a test to confirm that env variables will set non default values.  Also realized that I was errantly applying the env variables to the defaults for testing.  Understanding what this is doing more clearly I realize that should be clean.

* Refactoring to

1. Remove the test variables from the schema and defaults and manually reflect the tests in the test.

2. Rename environment variable base from ZIGBEE2MQTT_ to ZIGBEE2MQTT_CONFIG_

* Small improvements

* Removing the unneeded test.
