Config: Implement config override with env vars (#502)



* Config: Implement config override with env vars



Implement overriding of configuration from the .conf file with environment variables.

Environment variables keys are autogenerated based on the keys defined in .conf file.

Usage example:

$ export CM_DATA_DIR=/usr

$ CM_WORLD_SERVER_PORT=8080 ./mangosd



* Update env var key format and encapsulated env loading logic.



The new env key format:

Mangosd_Rate_Health

Mangosd_DataDir



* Add suggestions from code review.



* Add missing includes.
