V2 strategy - support for creating separate controller log files

[rapcmia]

Feature Suggestion

When testing v2 strategy using multiple controller configs, we observed that the log file is shared and its difficult to read or trace logs for a particular controller without looking into other controller events. This would also cause increase on the size of log files specially when hit by an issue or exchange related problems.

Impact

So when you create a script config with multiple controllers like below:

markets: {}
candles_config: []
controllers_config:
# - conf_directional_trading.bollinger_v1_1.yml
- conf_directional_trading.trend_follower_v1_1.yml
- conf_directional_trading.dman_v3_1.yml
- conf_market_making.dman_maker_1.yml
config_update_interval: 60
script_file_name: v2_generic_with_controllers.py

Instead of sharing all logs inside the script file name v2_generic_with_controllers.log, create log files that point to each of controller yml files, e.g conf_market_making.dman_maker_1.log
