Automatic HyperOpt run every X days

Hello, first of all, many thanks for this awesome library!

I am working on 5m timeframe strategies and found out that the profitable parameters can change from one week to another. Hence, I thought it might be time saving and efficient money-wise to add an 'Auto HyperOpt' functionality, that would, if turned on :

1. automatically run an hyperopt loop for x days, on a daily/weekly basis
2. compare with current parameters
3. pick up the best parameters and reload the config/strategy

The config.json file would thus need another section :

"autohyperopt": {
    "enabled" : true,
    "run_every_x_days": 1,
    "backtest_x_days": 5,
    "epochs": 100,
    "hyper opt_loss": SortinoHyperOptLossDaily,
    "compare_with_current_parameters": false,
}

Let me know what you think and if you like part of this idea or this idea as a whole. I'm looking forward to discussing it!
