463 Config environment variables interpolation required and nones (#467) 
* Make prototype with enterpolation before parsing

* Add test for option.from_yaml() with missing env not required

* Make some cosmetic changes to _resolve_config_env_markers()

* Add test for option.from_ini() missing envs not required

* Skip schema test cause it requires internet connection

* Add tests for .from_yaml() for config and config option

* Add tests for .from_ini() for config and config option

* Add example for os.environ.setdefault() and envs interpolation

* Add/update docs on environment variables interpolation

* Update changelog
