We've only tested the connector against the latest Vault version
available at release time. However, we do support a wider range.
Test against the oldest supported release, the latest with AppID
and the actual latest.
The AppID auth backend is removed in Vault 1.12 and prevents the process
from starting. We now enable the legacy tests conditionally depending on
the actual Vault version.
The official docs incorrectly state "replication_perf_mode" which was
renamed to "replication_performance_mode" way back in Vault 0.9. We now
use the correct field name that is emitted by the API.
