Code refactoring (whittlem#159)

* Move Telegram into chat package

* Move configuration parsing into a package
- remove duplicate
- create parsing functions for Coinbase and Binance
- change the way app's arguments are interpreted (dict instead of object) in order
to make possible to merge them with the configuration

* Move Binance and CoinbasePro into the package exchange
