Adding integration of derived source feature across diff paths

[tanik98]

Description

• Integrating derive source feature in get and search path
• Tested this integration for various cases.
• Added integration tests for all relevant paths like create/update/get/search/reindex.

Considerations:

• For the scenarios where we read from the translog, we have created the in-memory lucene index, which will ensure that we derive source from lucene docValues and stored fields only instead of reading _source directly from translog. This will help in making final resulted source consistent in terms of various fields(like Date, GeoPoint(we always return in lat/lon pair, input source can have different format like geohash)) where display format can vary as compared to suppkied format passed during ingestion.
