Migrate to new Neptune Analytics API

[michaelnchin]

The dataplane API in the newest release of Neptune Analytics contains several breaking changes, which we need to modify the notebook magics to account for.

• /status: Status endpoint was deprecated and removed
• /propertygraph/statistics: Statistics endpoint was deprecated and removed.
• /propertygraph/statistics/summary: Summary endpoint is simplified to /summary.
• /opencypher/status: openCypher bulk query status was simplified to /queries.
• /opencypher/status/{queryId}: openCypher individual query status and cancellation endpoint was changed to /queries/{queryId}.
