Bump bind-operator to v0.2.2 (config-hash rolling restart)

v0.2.2 stamps a config hash on the pod template so ConfigMap / keys
changes roll the StatefulSet automatically, instead of pods holding a
stale startup snapshot until manually deleted.

- Bump the operator image and the pulled CRD bundle to v0.2.2.
- Bump the bind-tsig-api image to v0.2.2.

CRDs are unchanged from v0.2.1, so the generated schemas need no update.
