Geyser: incorrectly ordered slot status notifications

[jeff-delonge]

Problem

Occasionally, for a given slot, my Geyser plugin receives an update_slot_status notification for Confirmed before receiving update_slot_status for Processed. This makes it difficult to track the current Confirmed state of the ledger in the Geyser plugin.

My understanding is that expected order of events for slot N is as follows (please correct me if I'm wrong):

1. All update_account notifications for slot N
2. update_slot_status: Processed
3. update_slot_status: Confirmed

Using v1.17.24.

Proposed Solution

Plugin developers can reorder the notifications when this happens, but this adds additional complexity to the plugin.
