feat: add retina mode support for perf-test and abstract common e2e setups

[ritwikranjan]

Description

This pull request includes several changes to the end-to-end (E2E) testing framework for the retina project. The main update is addition of running perf tests in advanced mode for Retina. The other updates involve the addition of new utility functions, refactoring of existing code for better modularity, and improvements to the performance testing workflow.

New Utility Functions:

• Added RetinaChartPath, RetinaAdvancedProfilePath, and KubeConfigFilePath functions to dynamically generate file paths. (test/e2e/common/common.go)

Refactoring:

• Moved the CreateAzureTempK8sInfra function to a new file azure_temp_infra_setup.go to modularize infrastructure setup. (test/e2e/infra/azure_temp_infra_setup.go)
• Removed redundant code and simplified the TestE2ERetina and TestE2EPerfRetina functions by using new utility functions and the CreateAzureTempK8sInfra function. (test/e2e/retina_e2e_test.go, test/e2e/retina_perf_test.go) [1] [2]

Performance Testing:

• Moved the performance test logic to a new file perf.go and added support for running tests in different retina modes (basic, advanced). (test/e2e/jobs/perf.go)
• Updated the PublishPerfResults function to include the retina mode in telemetry data. (test/e2e/scenarios/perf/publish-perf-results.go)

Code Cleanup:

• Removed unused imports and redundant code blocks from various files to improve readability and maintainability. (test/e2e/jobs/jobs.go, test/e2e/scale_test.go) [1] [2]

These changes collectively enhance the modularity, readability, and functionality of the E2E testing framework, making it easier to maintain and extend in the future.
