Bug
1482560: Do not flush tracelogger to disk unless specifically requested to do so r=sfink
When enabling the tracelogger, it will automatically spew the data to disk in the location specified by TLDIR or /tmp, if undefined. However, there needs to be a way to enable the tracelogger without spewing so that we can write this data as part of the gecko profiler JSON output, and ultimately visualized with perf.html.
