add TestUpdateStatus for horizontalpodautoscaler
**What this PR does / why we need it**:
add `TestUpdateStatus` for horizontalpodautoscaler， and remove the relevant `TODO TestUpdateStatus

**Special notes for your reviewer**:
**Release note**:

Currently setting watch cache size for a given resource does not disable
the watch cache. This commit adds a new `default-watch-cache-size` flag
to map to the existing field, and refactors how watch cache sizes are
calculated to bring all of the code into one place. It also adds debug
logging to startup to allow us to verify watch cache enablement in
production.
The order of the storage setup blocks in the setup for the autoscaling
API group was accidentally inverted, meaning that if the v2alpha1 API
group was turned on, it would be set to the preferred API group-version
for discovery.
This was unintentional; the latest stable version should (v1) should be
preferred instead.
