metrics: report: improve interface y axis divs

Browse Source 
Most of the time we have 0 interface errors or drops, so we pin the y
scale to '1', so we don't hit 'infinity' errors. That left us with a
strange y-axis label anomoly - as the axis was automatically divided
into 5 labels, and we got for some reason the sequence '0,0,0,1,1'.
That just plain looked wrong and confusing.
Fix it by using `pretty_breaks()` for the error/drop y axis, whilst
maintaining the `comma` count for the pod count y axis.
