Modify ingest_metadata to move fields to top level

[maxsibilla]

Specifically for Datasets we will have to modify the provenance schema to add files and metadata as these will no longer live inside of ingest_metadata. Triggers that utilize ingest_metadata.metadata will also have to be updated to support this.

Make the same changes that are being made on the HuBMAP side see the ingest_metadata field changes document and HuBMAP entity-api issue #748 and HuBMAP manual-data-ingest issue #333

• Do we modify all ingest_metadata in dev/prod neo4j or do we modify the triggers to handle both use cases?

[maxsibilla]

• Modify trigger method set_processing_information to grab data from top level fields metadata and ingest_metadata
• Modify data in Neo4j to reflect top level fields files and metadata
  • This will also apply to Publications
• Check for any other instances of ingest_metadata.metadata inside of trigger methods or calculated fields
