Do not count soft-deleted pods for scaling purposes in HPA controller

**What this PR does / why we need it**:
The metrics of "soft-deleted" pods in general to be deleted should probably not matter for scaling purposes, since they'll be gone "soon", whether they're nodelost or just normally delete.

As long as soft-deleted pods still exist, they prevent normal scale up.

**Release note**:

Stop counting soft-deleted pods for scaling purposes in HPA controller to avoid soft-deleted pods incorrectly affecting scale up replica count calculation.
