Improve MinEventInterval compliance with docs
Description
In the command line arguments, we see min-event-sync-interval as "The minimum interval between two consecutive synchronizations triggered from kubernetes events"
In the code, it actually acts a different way.
It imposes a certain dealy between syncs. While this is compliant with the "minimum delay between 2 consecutive synchronizations", it has side-effects in case of large delays.
In particular, when trying to fine-tune external-dns to match the provider rate-limits.
In this case, it may be interesting to restrict the rate of reconciling actions happening by having a high min-event-sync-interval, while keeping a low latency for initial events.
This would allow to maximise the bulk effect of high change rate while keeping fast enough reaction for isolated changes.
