Problem Statement
In production usage, a db may be reopened in a multi-node env with both leaders and followers present. There needs to be clear, well-defined expectations. Without this clarity and corresponding test coverage, we risk gaps between expected and actual behaviour in production-like scenarios.

Description
Currently, test/format supports reopening a db in disagg mode for leader, follower, and switch configs. However, this functionality does not work correctly when running in multi-node.
This could be a test limitations, unclear usage of the API when reopening a multi node disagg db or even a big in WT. Because of these issues, test/format cannot reliably reopen databases in multi-node.

Goals

Allow test/format multi-node to successfully reopen databases and continue execution.
