[tmilos77]

• prevent overwhelming reconciler outcome log entries when Scope did nothing

Description

Changes proposed in this pull request:

• Scope reconciler do not add finalizer when Kyma has deletionTimestamp to prevent error message Kyma.operator.kyma-project.io "xxxx" is invalid: metadata.finalizers: Forbidden: no new finalizers can be added if the object is being deleted, found new finalizers []string{"cloud-control.kyma-project.io/deletion-hook"}
• do not log Scope reconciler outcome to avoid majority of produced logs when Scope did nothing due to frequent KLM changes to Kyma

We should look into adding additional log levels, so we can actually turn on these logs on demand when necessary (e.g. debug level).
