[BWC] Ensure 2.x compatibility with Legacy 7.10.x (#1902)
* [BWC] Ensure 2.x compatibility with Legacy 7.10.x

This commit fixes TransportHandshaker to send a spoofed Legacy 7.10.2 mincompat
version to ensure OpenSearch 2.x nodes can join a Legacy 7.10.x cluster for
rolling upgrade support. Without this change 7.10.x and OpenSearch 2.x mixed
cluster bwc tests would fail.
