Pull request overview

Backmerge bringing in cluster/INFO/migration improvements, plus dependency/tooling updates and additional test coverage across the Garnet test suites.

Changes:

• Add new INFO option aliases (ALL/DEFAULT/EVERYTHING) and update INFO help text and parsing behavior.
• Update CLUSTER SHARDS / CLUSTER NODES formatting (ip/endpoint/hostname fields, preferred endpoint selection) and strengthen cluster/migration test coverage (including tombstones and cleanup waits).
• Improve server accept-loop robustness under resource pressure and add a Tsavorite revivification pause handshake used by migration.

• The otherPorts filter uses x != sourcePort || x != targetPort, which is always true (a port cannot equal both values at once), so it won’t exclude sourcePort/targetPort from the set. Use an AND condition (exclude when equal to either) so the subsequent loop only checks the other nodes as intended.

            context.clusterTestUtils.WaitForMigrationCleanup(logger: context.logger);
            context.logger.LogDebug("6. Checking configuration update starting");
            // Check if configuration has updated by
            var otherPorts = context.clusterTestUtils.GetEndPoints().Select(x => ((IPEndPoint)x).Port).Where(x => x != sourcePort || x != targetPort);
