Use the last transition time to track and assess status conditions

[leochr]

The unchangedConditionCount field in the status condition can interfere with updating CR, especially at the initial stage when the reconcile interval is 5 seconds. Eventually, it'll only be updated every 120 seconds, but can still be disruptive.

We should consider using the lastTransitionTime instead (if appropriate, otherwise lastUpdateTime) to determine when to increase the reconcileInterval. In some cases, the status condition and lastTransitionTime are not set/updated correctly, so that must be resolved first.

If the above is possible, then we should also support a configuration option to disable .status.reconcileInterval field (i.e. reconcileIntervalHide), so that users are not interrupted by status updates when trying to update CR spec.
