This reverts commit 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:
#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.
