nit : lets fix this to contain actual info
An example :
@Override
public String toString(String field) {
return "BinaryDocValuesRangeQuery(fieldName=" + field + ",from=" + originalFrom + ",to=" + originalTo + ")";
}

This method is used to Prints a user-readable version of this query.
- since this is not exposed to user and is utilized internally, I'm planning to return null here, and for OriginalOrStarTreeQuery class - I am thinking of printing the originalQuery::toString. How does this sounds?

Disclaimer
These changes are built on top of unmerged/in-review indexing changes, Reviewers kindly ignore this commit while reviewing this change. When the depending changes are merged, will remove theDo not merge
from title, and addchngelog
to the PR - avoiding adding now to avoid unnecessary rebasing/conflicts.Description
For an index supporting star-tree composite index, this changes tries to achieve resolving a metric aggregation with/without a numeric terms query with the help of star-tree.
In present state, the PR capture changes for sum, max, min, avg, value-count aggregation.
Once the high level changes in sum aggregation are reviewed, will increment with other aggregations.Approach
A new StarTreeQuery is introduced which helps resolve to star-tree documents. This star-tree query is formed (if it can be) at the shard level, this is not done at coordinator level to avoid node to node transportation. Also, all the information is present at shard level and OpenSearch does majority of query rewrite at shard level itself. This star tree query is encapsulated in an OriginalOrStarTreeQuery which helps preserve the original query alongwith the new star tree query. This encapsulation is done so as to preserve both the queries and decision whether to use which query can be taken at a segment level.
