Pull Request Overview

This PR adds a new telemetry callback mechanism to the Broker Discovery Client to enable OneAuth to measure performance metrics during broker discovery operations. The changes introduce a new interface IBrokerDiscoveryClientTelemetryCallback with methods to track timing for various discovery stages, and adds an overloaded getActiveBroker method that accepts this callback as a parameter.

Key Changes

• Added IBrokerDiscoveryClientTelemetryCallback interface defining 6 callback methods for tracking performance metrics during broker discovery
• Extended IBrokerDiscoveryClient interface with new getActiveBroker overload accepting the telemetry callback
• Implemented telemetry callback support in BrokerDiscoveryClient with timing measurements for cache reads, package validation, and broker queries
• Added stub implementation in LegacyBrokerDiscoveryClient that ignores the callback (as documented)

Looking for a tag to measure time waiting for lock, and then we're good. Chase and I looked together so I'm signing off for both of us.
