- Around line 2621-2624: Move the `healthCheckBackoff.forget(key)` call out of
the `strategyErr == nil` check near `CheckInstalled`; a successful strategy
check alone does not mean all install checks passed. Reset the per-CSV backoff
only in the branch where `strategyInstalled`, `apiServicesInstalled`, and
`webhooksInstalled` are all true, before returning success.

Reset health backoff only after all install checks pass.
CheckInstalled only validates the deployment strategy. It can return no error while an APIService or webhook is still unavailable. The current reset then clears the CSV backoff before those checks run. A later waiting error can therefore restart at 10 seconds instead of using the next per-CSV delay.

Closing this, because olmv0 is in maintenance mode |
Description of the change:
implements per-CSV healthcheck retry backoff approaches. In order to attempt to split the difference between responsiveness and not pummeling the cluster with checks, it becomes necessary to track and pursue backoff individually per CSV.
Motivation for the change:
By design, OLMv0 is pretty aggressive about assessing health of deployed CSVs. In some cases with either constrained capacity or arbitrary event limits, this can add noise to an eventually-consistent process.
https://redhat.atlassian.net/browse/OCPBUGS-127050 identified cases where the event count was deemed pathological.
