add daily_profit_list

added extra key daily_profit in return of optimize_reports.generate_daily_stats
this allows us to analyze and plot a daily profit chart / equity line using snippet below inside jupyter notebook

```
# Plotting equity line (starting with 0 on day 1 and adding daily profit for each backtested day)

from freqtrade.configuration import Configuration
from freqtrade.data.btanalysis import load_backtest_data, load_backtest_stats
import plotly.express as px
import pandas as pd

# strategy = 'Strat'
# config = Configuration.from_files(["user_data/config.json"])
# backtest_dir = config["user_data_dir"] / "backtest_results"

stats = load_backtest_stats(backtest_dir)
strategy_stats = stats['strategy'][strategy]

equity = 0
equity_daily = []
for dp in strategy_stats['daily_profit']:
    equity_daily.append(equity)
    equity += float(dp)

dates = pd.date_range(strategy_stats['backtest_start'], strategy_stats['backtest_end'])

df = pd.DataFrame({'dates':dates,'equity_daily':equity_daily})

fig = px.line(df, x="dates", y="equity_daily")
fig.show()
