Bugfix/s3 utils 239 fix count items bucket logging

[benzekrimaha]

In the PR we are nullifying _bucketLoggingStatus which is safe for count-items specifically: that this metadata is unrelated to object count / storage usage computation and only exists on the BucketInfo object because it is part of the full bucket metadata model.
The implementation we now have is cleaner and makes this explicit by naming the fields as unsupported serialized BucketInfo fields for count-items.
The rationale being that : class-backed fields that count-items does not consume should not be rehydrated in the worker path just to count object metadata.

could have kept the comment about why we do this 🤔

[maeldonn]

Once normalizeBucketInfoForCountItems updated, it will be good for me !

[maeldonn]

nit:

Suggested change

	const unsupportedSerializedBucketInfoFields = [
	const UNSUPPORTED_SERIALIZED_BUCKET_INFO_FIELDS = [

[maeldonn]

Using object spread inside a reduce loop creates a brand new copy of the object on every iteration, leading to big time complexity and heavy memory churn. We can optimize this by cloning the object just once and using a for...of loop to safely update the properties.

Suggested change

	function normalizeBucketInfoForCountItems(bucketInfoObj) {
	function normalizeBucketInfoForCountItems(bucketInfoObj) {
	const normalized = { ...bucketInfoObj };
	for (const field of unsupportedSerializedBucketInfoFields) {
	if (normalized[field]) {
	normalized[field] = null;
	}
	}
	return normalized;
	}
