A IMetricCollector that collects traces during the test using trace-cmd, and logs them to
the invocation.
This trace collector allows for USB disconnection during the test (as in power testing).
The system default tool, atrace, is used in tandem with this collector to set the android-specific sysfs flags.
A trace-cmd (https://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git) binary compatible with Android must be specified.
This will upload the trace.dat format (see man 5 trace-cmd.dat) produced by trace-cmd.
