b584b87a94 kube-controller-manager: readjust log verbosity 
- Increase the global level for broadcaster's logging to 3 so that users can ignore event messages by lowering the logging level. It reduces information noise.
- Making sure the context is properly injected into the broadcaster, this will allow the -v flag value to be used also in that broadcaster, rather than the above global value.
- test: use cancellation from ktesting
- golangci-hints: checked error return value

3c4512c6cc hpa: always update status metrics when updating the replica count 
Have hpa always update both the metrics and replica count. This fix an
edge case behavior bug where the metrics would not be updated if a
custom metrics was unavailable.

f428705ec6 Fix comment in HPA's scale event replicaChange 
The field replicaChange in timestampedScaleEvent was wrongly described
as either positive or negative depending on the scale direction. In
fact the change is set as unsigned, positive or 0 even for downscales.

Fix replica calculation at start of HPA scaling policy period 
When calculating the scale-up/scale-down limit, the number of replicas
at the start of the scaling policy period is calculated correctly by
taken into account the number of scaled-up and scaled-down replicas.

16133c2b77 Up and down scale stabilize with envelope. 
The HPA controller keeps a flat history of recommendations for
stabilization. However when both up and down scale stabilization are
configured, the interpretation of the history changes depending on the
direction of movement. What we want is to keep the stabilized
recommendation within the envelope of the minimum and maximum over
configured stabilization windows. We should only move when the
envelope forces a move.
