Refactor config to use environment variables

[ricardopadilha]

This refactor of config.ts allows easier Docker deployment, since every config option is exposed as an environment variable, while preserving the existing default values.

Typical docker compose file after this change:

  server:
    image: wppconnect-server:2.8.6
    volumes:
      - wppconnect_token_data:/usr/src/wpp-server/tokens
