User name during manual block deleting

Requirements

Find the most effective approach (effort + implementation complexity).

APPROACH 1: Retrieve user id from the headers when deleting record and re-send it in the metadata during manual block deleting flow.

Steps to implement:

1. Change org.folio.rest.impl.ManualBlocksAPI in mod-feesfines module by adding the following line in the deleteManualblocksByManualblockId method:

   String source = okapiHeaders.get("x-okapi-user-id");
   JsonObject payload = JsonObject.mapFrom(getByIdReply.result());
   payload.getJsonObject("metadata").put("updatedByUserId", source);
   
   

2. Change org.folio.builder.service.ManualBlockRecordBuilder in mod-audit module by changing the logic in the getSource method where 'source' is alwaysnull when log event type is MANUAL_BLOCK_DELETED (requires minimum effort).

As a result, mod-audit can recognize source correctly: https://github.com/folio-org/mod-audit/blob/master/mod-audit-server/src/main/java/org/folio/builder/service/ManualBlockRecordBuilder.java#L46.

APPROACH 2: Change deleting flow, introduce fake deleting with key isDeleted to mark manual block as deleted. One need to change all CRUD operations.

Steps to implement:

1. Change manual patron block schema by adding additional field 'isDeleted' that can be true or false (initially false).
   
2. Change org.folio.rest.impl.ManualBlocksAPI in mod-feesfines module by adding filter in getManualblocks method to return manualblocks only with isDeleted=false.
3. Change org.folio.rest.impl.ManualBlocksAPI in mod-feesfines module by adding filter in getManualblocksByManualblockId method to return manualblock only if isDeleted=false.
4. Change org.folio.rest.impl.ManualBlocksAPI in mod-feesfines module by setting isDeleted field in Manualblock entity to 'true' in deleteManualblocksByManualblockId method

As a result, all 'delete' operations are stored in manualblocks table, and user id can be found in updatedBy column using RMB.
