What/Why

What are you proposing?

I've run in the same high CPU usage with opensearch-java as with elasticsearch-java (elastic/elasticsearch-java#471), there they added a LookAheadJsonParser for Jackson (elastic/elasticsearch-java#489) to fix that high CPU usage, and the code that the PR changed exists in opensearch-java.
So I propose to port that fix to opensearch-java.

What problems are you trying to solve?

@luneo7 We will gladly accept a PR if the code comes from anything compatible with the APLv2 license!
