Make Backtest functional

[MHHukiewitz]

Feature Suggestion

Unit tests prepared here, fixes work in progress: #5

ToDo:

V1

• Make the backtest run on any connector, using the API

V2

• On the frontend: Use Jupiter as the exchange, and list all (or have searchable) tokens on Jupiter
  • Use Birdeye API to fetch and forward to frontend
• NOTE: Backtesting is only available for strategies V2
• Check out Hummingbot codebase to determine how to integrate Birdeye API as a Backtest data source, integrate in our own fork
• Write a V2 strategy that uses Gateway/Jupiter to do simple swaps

Impact

Run the backtest with metrics for the frontend.
