Create e2e test suite

[nikola-jokic]

This pull request introduces a major update to the end-to-end (E2E) testing infrastructure for GitHub Actions runners. The main changes add version 2 ("-v2") variants of all existing E2E test jobs in the .github/workflows/gha-e2e-tests.yaml workflow, refactor test execution into a new script (hack/e2e-test.sh), and provide dedicated shell scripts for each test scenario. These updates improve maintainability, modularity, and flexibility of the E2E test suite, making it easier to run individual tests and add new scenarios.

E2E Test Workflow Enhancements

• Added new "-v2" job variants for all major E2E test scenarios (default-setup-v2, single-namespace-setup-v2, dind-mode-setup-v2, kubernetes-mode-setup-v2, auth-proxy-setup-v2, anonymous-proxy-setup-v2, self-signed-ca-setup-v2, update-strategy-tests-v2, and init-with-min-runners-v2). These jobs leverage the new test scripts and only run for PRs from the same repository. [1] [2] [3] [4] [5] [6] [7] [8] [9]

Test Execution Refactoring

• Introduced hack/e2e-test.sh, a new script that manages environment validation, test selection, and execution for all E2E scenarios, allowing easy running of individual or all tests.
• Added a new gha-e2e target to the Makefile to invoke the new test runner script.

Scenario-Specific Test Scripts

• Added dedicated shell scripts for each test scenario under test/actions.github.com/, including default-setup.test.sh, auth-proxy-setup.test.sh, and anonymous-proxy-setup.test.sh, each encapsulating the setup, execution, and teardown logic for its respective environment. [1] [2] [3]

Other Minor Improvements

• Removed unused build arguments (RUNNER_VERSION, DOCKER_VERSION) from the docker-buildx target in the Makefile for cleaner builds.

These changes collectively modernize and modularize the E2E testing pipeline, making it easier to maintain and extend.

Pull Request Overview

This PR introduces a new end-to-end testing framework for GitHub Actions Runner Controller (ARC) using bash scripts and minikube. It adds multiple test scenarios covering different deployment configurations and a test runner script to execute them.

Key Changes:

• Added 9 new test scripts covering various ARC deployment scenarios (default, single-namespace, dind-mode, kubernetes-mode, proxy configurations, self-signed CA, update strategy, and min runners)
• Created a shared helper library (helper.sh) with common functions for cluster management, ARC installation, and workflow execution
• Added test runner script (hack/e2e-test.sh) to orchestrate test execution
• Integrated new tests into GitHub Actions workflow with v2 variants of existing test jobs
• Added gha-e2e target to Makefile and removed unused Docker build arguments
