Add a new method to get config from environment variables
and for now, we have three ways to get config and the
priority is `env-var > custom-config-file > built-in-config-file`.

confuse users when they get config value is `var-env` but value
in the configuration file is `var-in-file`, they may not find
the way how to change it
