Add dynamic debug logs to VelocityTracker
This will allow us to debug any issues related to the switch to the
'impulse' velocitytracker algorithm.
In addition, print the lsq2 velocity values for the case when 'impulse'
is selected, and when debugging is enabled. This will make it simpler
for us to follow up on dogfooder's feedback.
