[DEPR]: Neo4J Support

Earliest Open edX Named Release Without This Functionality

Sumac 2024-10

Rationale

We would like to take out neo4j support from edx-platform and remove it as a dependency from edx-platform. We believe this library and its usage is underused and not particularly valuable as many operators have switched to searching course data in other types of data stores.

Removal

Removal of https://github.com/openedx/edx-platform/tree/master/cms/djangoapps/coursegraph and the neo4j library from edx-platform. If anyone wants to keep this functionality, a separate plugin can be created.

Replacement

We do not have a replacement.

For folks looking for a replacement, Aspects we've emulated much of what Coursegraph does in ClickHouse via openedx-event-sink-clickhouse (which currently has a DEPR, but just to consolidate the code with other Aspects plugins in platform-plugin-aspects). It's not 1:1, but can help answer some of the same questions.

@bmtcril could you please review my PR?

According to @dianakhuang 's DEPR this is supposed to remain through Sumac. I assume to let the community have one release of warning before the removal. @qasimgulzar are you proposing to merge this sooner?
