Pull Request Overview

This PR enhances benchmark reporting by pushing benchmark results to Grafana via Prometheus metrics while updating benchmark tests to run only in CI. Key changes include:

• Adding a Prometheus gauge vector (benchmarkDuration) and integrating it within EvaluateBenchmarkResults.
• Removing local performance thresholds in favor of external metric push.
• Updating benchmark tests and CI pipelines to ensure proper CI environment variables and service initialization.

• Consider externalizing the Pushgateway URL (currently hard-coded as 'http://localhost:9091') to an environment variable, so the configuration becomes more flexible and environment agnostic.

if err := push.New("http://localhost:9091", "api_benchmark").Collector(benchmarkDuration).Push(); err != nil {

• [nitpick] The parameter 'testCase' is passed a variable named 'name' from the tests; consider renaming it (for example, to 'benchmarkCase') to ensure consistent and clear naming across the codebase.

func EvaluateBenchmarkResults(b *testing.B, testCase string, duration time.Duration, recorder *httptest.ResponseRecorder, module string, operation string) {
