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.

+
+Indexer service support r3 schema. These schemas are created via Schema service. 
+
+Here is an example following end-to-end workflow can be exercised (please update the schema based on your environment):
+
+* Ingest r3 schema for `opendes:wks:master-data--Wellbore:1.0.0`. Schema service payload can be found [here](https://community.opengroup.org/osdu/platform/system/indexer-service/-/blob/master/testing/indexer-test-core/src/main/resources/testData/r3-index_record_wks_master.schema.json).
+
+* Ingest r3 master-data Wellbore record. Storage service payload can be found [here](https://community.opengroup.org/osdu/platform/system/indexer-service/-/blob/master/testing/indexer-test-core/src/main/resources/testData/r3-index_record_wks_master.json)
+
+* Records can be searched via Search service. Here is sample payload:
+
+```
+POST /api/search/v2/query HTTP/1.1
+Content-Type: application/json
+data-partition-id: opendes
+{
