Get raw data endpoints

[pgrill]

• Add the /reports/{camera_id}/daily_data endpoint to retrieve the daily CSV file without any analysis
• Include the webhooks support in loggers
• Refactor the loggers removing unused code.

As these two loggers have a log_objects function with the same signature, I am tempted to do something like this:

for logger in [logger1, logger2]:
    logger.log_objects(...)

That would be nice if you plan to support multiple loggers, otherwise might not be that helpful.

What do you think?

I think that this is a good idea.

I changed the logger implementation structure following the pattern you suggested.
