**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.
**Checklist**
- [X] Unit tests updated
- [X] End user documentation updated
> End user documentation matches the updated behaviour with more
> accuracy

the entire logic of missing endpoints was removed from the controller
taking leverage on the planner

This change tries to remove part of the logic added in 50f196c0db.
The forceUpdate strategy relies on existing code of the planner to migrate TXT records to the new format,
being the main goal to avoid conflicts during apply.

Changes to add A records of source and registry as metrics. The existing metrics -
external_dns_registry_endpoints_total & external_dns_source_endpoints_total gives a cumulative count of records all records (A, SRV, CNAME, TXT).
We have a metric - external_dns_controller_verified_records which gives the intersection of A records between source & regsitry. However, in order to determined how many records are yet to be synced to registry, we need count of total A records in registry & source.
Currently, planning instructs to create all records even
those which does not match any zone.
Later, those records will be checked towards the existing
records and filtered whether they match or not a hosted zone.
This causes a problem, at least in the specific case of the Route53
implementation as it always calls the ApplyChanges method, which in its
turn always retrieves all records in all zones.
This causes high pressure on Route53 APIs, for non-necessary actions.
By being able to filter all unmanaged records from the plan, we can
prevent from calling ApplyChanges when nothing has to be done and hence
prevent an unnecessary listing of records.
By doing so, the rate of API calls to AWS Route53 is expected to be
reduced by 2
Currently, the minimum delay between 2 kubernetes events handling is
hard-coded to 5s.
This may cause higher synchronization rates and higher DNS provider API
calls when handling an important number of kubernetes events at once.
Give the opportunity to configure this delay so service owners can
define the acceptable thresholds on their side
