Determine which init system a particular linux distro is using.
Each init system (systemd, etc) has a different way of
providing timestamps.
:return: timestamps of kernelboot, kernelendboot, and cloud-initstart

Take in raw events and create parent-child dependencies between events
in order to order events in chronological order.
:param events: JSONs from dump that represents events taken from logs
:param blame_sort: whether to sort by timestamp or by time taken.
:param print_format: formatting to represent event, time stamp,
and time taken by the event in one line
:param dump_files: whether to dump files into JSONs
:param log_datafiles: whether or not to log events generated
