Use cluster recommendations when creating tunnels in the Java SDK

[Arun G (ArunGopinathan)]

Changes proposed:

• Use the cluster recommendations API when the Java SDK creates a tunnel.
• Authenticate recommendation requests and retry anonymously only when authentication is rejected.
• Preserve global routing as a fallback and report the selection outcome through X-Tunnel-Cluster-Source.
• Add deterministic coverage for recommendation results, authentication fallback, query parameters, caller-owned options, and telemetry headers.

Other Tasks:

• If you updated the Go SDK did you update the PackageVersion in tunnels.go
• If you updated the TS SDK did you update the dependencies in package.json for connections and management to require a dependency that is > the current published version(Found using npm view @microsoft/dev-tunnels-contracts). This will fix issues where yarn will pull the old version of packages and will cause mismatched dependencies. See example PR
