Gateway V2 Code Architecture part 2

Gateway V2 is a major overhaul to the Gateway system, in which Hummingbot uses to communicate with decentralized markets such as Uniswap and Pangolin. Compared to the original Hummingbot Gateway, Gateway V2 adds major improvements to the reliability, user experience and security.

Script Strategies

This release also introduces a simplified version of the trading strategies called Script. The scripts are intended to be used without requiring a configuration. All data used by the script should be included in the script file.

The script is a Python class. It can be created by subclassing the new ScriptStrategyBase class. All scripts modules should be stored in the /scripts folder (the old scripts folder is renamed to pmm_scripts). There is a new version of the start command for the scripts: start --script <script_module_name>
