Feature/query offering

Dear Denis,Natallia,

This is a request to add our new changes to the branch main which we figured when we wanted to resolve https://gitlab.com/gaia-x/data-infrastructure-federation-services/cat/fc-service/-/issues/65 . The Neo4jGraphStoreTest has a new test which returns count of locality and the locality. Other than that we have changed the addClaims method where we pass the claimList to validateclaims class instead dealing with claims one by one to preserve the ID of the blank node. The same logic is extended to extend claims where we pass the entire list to extendclaims instead of passing one claim after another. This has caused some significant changes in the logic. Please have a look and we will resolve threads soon if there are any. Unfortunately we saw this issue later.

Thank you for your understanding Wish you a nice day Best Regards Nikhil Acharya
