Add file rotation for logger

[Fullstop000]

Currently, we use a simple file to store all log messages:

wickdb/src/logger.rs

Lines 54 to 58 in 15c37cc

	let file = storage
	.create(generate_filename(db_path, FileType::InfoLog, 0).as_str())
	.unwrap();
	slog_async::Async::new(FileBasedDrain::new(file))
	.build()

This could be a bad design as the log messages growing. Adding a file rotation by implementing a slog Drain might be a good solution.
