Better Logging to help understand trade logic

### Enhancement description

Currently, it is impossible to know why a position was closed or opened without clear logs explaining the reasons.

Also, a trade id to identify all trades is needed.

### Code sample

```python
self.buy(log="The position was opened")

self.sell(log="The position was opened")

self.position.close(log="The position was closed because???")

trade.sl(price=???, log="Take stop loss was reached")

trade.tp(price=???, log="Take profit was reached")
```

Start by tracing the buy, sell, position.close, trade.sl, and trade.tp entry points shown in the issue. Determine how logging and trade identity are currently handled across these operations; done means logs explain why positions or trades opened and closed and a trade ID identifies related activity.
