add support for feature-collection indexing

Data Definition team has harmonized the geo-shape payload on bulk-records. Any records that has geo-shape, must be GeoJson and must conform to the schema mentioned here. All shapes must be put in FeatureCollection.

Earlier implementation of indexer service was missing this key shape hence geo-shape indexing and search workflows was broken.

This MR adds support for FeatureCollection indexing. It also adds official opendes:wks:master-data--Wellbore:1.0.0 as integration test to validate index and search workflow.

This MR also fixes few schema parsing errors which we discovered while enabling opendes:wks:master-data--Wellbore:1.0.0 indexing.
