Add new sources to Recorded Future external-import

[ryano-recordedfuture]

Use case

We would like to add a new source of analyst note topics to the analyst note import that have recently came available. Currently if you do not specify the RF Topics to include all ids except the two undefined source, the connector will throw errors when trying to convert to stix format.

{ "timestamp": "2024-05-08T17:38:40.817916Z", "level": "ERROR", "name": "Recorded Future", "message": "No values for required properties for Report: (object_refs).", "exc_info": "Traceback (most recent call last):\n File \"/opt/opencti-connector-recorded-future/main.py\", line 176, in run\n self.convert_and_send(published, tas, work_id)\n File \"/opt/opencti-connector-recorded-future/main.py\", line 222, in convert_and_send\n bundle = stixnote.to_stix_bundle()\n ^^^^^^^^^^^^^^^^^^^^^^^^^\n File \"/opt/opencti-connector-recorded-future/rflib/rf_to_stix2.py\", line 1115, in to_stix_bundle\n return stix2.Bundle(objects=self.to_stix_objects(), allow_custom=True)\n ^^^^^^^^^^^^^^^^^^^^^^\n File \"/opt/opencti-connector-recorded-future/rflib/rf_to_stix2.py\", line 1099, in to_stix_objects\n report = stix2.Report(\n ^^^^^^^^^^^^^\n File \"/usr/local/lib/python3.11/site-packages/stix2/base.py\", line 215, in __init__\n raise MissingPropertiesError(cls, missing_kwargs)\nstix2.exceptions.MissingPropertiesError: No values for required properties for Report: (object_refs)." }

Current Workaround

Proposed Solution

Adding the new source topic to the report_type_mapper

connectors/external-import/recorded-future/src/rflib/rf_to_stix2.py

Line 896 in 3c775c4

report_type_mapper = {

"Executive Insights": "Threat-Actor"

Based on example received, must be imported as Reports with external references. context_entities are too generic to be included.
