[release-1.9] Scheduler doesn't reschedule vpods that are scheduled on unscehdulable pods #6730

This is an automated cherry-pick of #6726

…e pods

To detect whether scheduling is already done, it uses the existing
placements fields, however, if one or more placements are for
unschedulable pods, it won't reschedule them.

See added unit tests for example scenarios.

* [release-1.9] Revert "Change subscription patch logic to ensure resource version (knative#6670) (knative#6725)

This reverts commit
knative@4d6e1fc.

It has the side effect of dropping channel spec fields, so even
immutable
fields are dropped, hence channels will fail to get updated.

We need to re-evalute the approach to fix the orginal issue:
knative#6636, patch will always
have edge cases that will lead the original bug because subscriptions
are reconciled independently from each other (and potentially by
multiple controller replicas), so update is the only way of having
concurrency control at the resource level but we should make sure
that we're preserving unknown fields when updating channelables.
