By piggybacking off an existing process that we have within ingest-to-sds, we're aiming to remove the dependency on another microservice to provide indexing of ingested granules. Aside from minor changes to ingest-to-sds last week, this work also encapulates work within swodlr-api in order to utilize the indices generated to provide a valid/invalid check for frontend use
