Implementation of a endpoint used for the ingestion of the data score

https://github.com/panosc-eu/panosc-search-scoring

The scoring has its own database where public datasets will be ingested. It is a mongo DB which model is called item: https://github.com/panosc-eu/panosc-search-scoring/blob/master/docs/md/PaNOSC_Federated_Search_Results_Scoring_API.md#model

This item will be used to be ingested into its database. We need to implement a webservice that converts a dataset into an item
