When enabling the advanced setting `courier:ignoreFilterIfFieldNotInIndex`
Custom OpenSearch Query DSL filters could technically be applied to index
patterns that map to indices that are not exactly the same. Since the
custom query filter is a user input then users can really type anything
that they need. Or any field that they know is present but we do not know
for sure.

Therefore, we can check if the id which is the index pattern title to check
if we should apply the filter or not.

I believe issue:
opensearch-project#5423

Should closed as that is expected functionality.

Originally when implementing the fix the historical comment caused concern about
potential breaking changes.

But after discussion, we decided it is more clear to consolidate the helper functions.
