OGM-1581 Investigate work necessary to upgrade remote Neo4j to Bolt >= 4.

[michael-simons]

This is a draft what is necessary of a more or less mechanical update.

Please see the prose here https://hibernate.atlassian.net/browse/OGM-1581

Open issues (at least)

• Parameter name syntax: {name} is no longer available in Neo4j 4.x, instead $name must be used
• The index tests fails: Syntax of what's being returned from the server as information about indexes changed quite a lot
• Probably session / result usages at some areas, such as in the test helper. The drivers session is now much more opinionated about accessing the result set after the session has been closed

This is not in hurry at all and I just like to leave this as a thing to discuss.
