Merge pull request #41911 from ixdy/bump-rescheduler

Automatic merge from submit-queue (batch tested with PRs 41854, 41801, 40088, 41590, 41911)

Bump gcr.io/google-containers/rescheduler to v0.2.2

**What this PR does / why we need it**: updates the rescheduler image to one based on busybox instead of ubuntu-slim. Changes for the image were in kubernetes-retired/contrib#2390.

Do you think this merits a release note? I'm leaning towards no.

**Release note**:

```release-note
Update gcr.io/google-containers/rescheduler to v0.2.2, which uses busybox as a base image instead of ubuntu.
```
