recent transition time lock can block reconciliation if only sub resources have been changed

[raffis]

Describe the bug

If only sub resources have been changed and spec.interval is set to a high number reconciliation
is awaiting the interval.
However this does not happen if the realm generation was changed.

To Reproduce

Change a keycloakclient or user.

Expected behavior

It should trigger a reconcile. The generations of the observed sub resources have to be acknowledged as well.

Environment

• controller version: v2.0.7

Additional context

This gate exists to avoid unnecessary pod scheduling of realm reconcilers.
