Add CBT events to Onionperf result files
As I understand this, the results should record whether the CBT was set at the time of measurement. This could just be a CBT_SET True/False field in the tpf results file. The CBT resets in certain conditions, and this should be reflected in the results. The events should be parsed from the tor logs. We should check with Mike if this meets the requirements.
