add GitHub Actions for e2e test

[u110]

This pull request adds a new GitHub Actions workflow file to run end-to-end (E2E) tests for the project. The workflow is configured to run on pushes and pull requests to the main branch, with different job conditions based on the actor initiating the workflow.

Key changes include:

• Added a new workflow file .github/workflows/e2e_test.yml to define E2E tests.

Workflow configuration:

• The workflow triggers on push and pull request events targeting the main branch.
• Defined two jobs: e2e_test for specific team members and e2e_test_for_others for other contributors, with conditional execution based on the actor.
• Set up the jobs to use specific versions of actions/checkout, actions/setup-go, and hashicorp/setup-terraform actions.
• Configured environment variables and steps to run the E2E tests, including downloading Go modules and executing make testacc.
