Nicolas Pitre e982bf71c5 tests: timer_behavior: jitter test using timer start delay and period 
Exercize both the timer start delay as wellas the timer period and
gather stats for each.

# Test a timer implementations variance and long term drift

Records and calculates statistical values against a timer validating that.

1. Timer variance and standard deviation is below defined acceptable values.
2. Periodic timers do not drift in either direction from expected total time.

Timers are meant to be precise and accurate. This test validates an implementation is both.
