Adding OTG Utility Function

[ANISH-GOTTAPU]

This Utility function will do a polling mechanism to check if the Transmit packets received at the far end.

Usage:

	otgutils.WaitForTxPacketsReceived(t, otgutils.TrafficTestParams{Config: otgConfig, Ate: ate})

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request adds a new utility function to the internal OTG package to streamline traffic validation. By providing a standardized way to wait for packet convergence, it simplifies the testing process for verifying that transmitted packets match received counts across configured flows.

Highlights

• New Utility Function: Introduced WaitForTxPacketsReceived to facilitate traffic verification in OTG tests.
• Polling Mechanism: Implemented a polling-based approach using gnmi.Watch to ensure transmitted packets are successfully received at the far end.

Code Review

This pull request introduces a new utility function, WaitForTxPacketsReceived, in internal/otgutils/traffic.go to monitor and wait for traffic convergence across OTG flows. Feedback suggests optimizing the implementation by watching the Counters() node directly to avoid inefficient gnmi.Get calls within the watch loop and refactoring the sequential flow processing to run in parallel or use wildcard paths for better performance.
