[Infra] Remove flaky proxy_e2e_azure_batches_tests CI workflow

[yuneng-berri]

Summary

Problem

The proxy_e2e_azure_batches_tests workflow is consistently flaky — it fails intermittently regardless of code changes, providing no reliable signal on whether a PR actually breaks anything. This leads to wasted CI minutes, unnecessary re-runs, and developer friction when legitimate PRs are blocked by unrelated test failures.

Fix

Remove the proxy_e2e_azure_batches_tests workflow entirely from both CircleCI and GitHub Actions, along with the test directory it exclusively used.

Changes

• Removed the proxy_e2e_azure_batches_tests job definition from .circleci/config.yml
• Removed its workflow trigger entry from the CircleCI workflows section
• Removed .github/workflows/test-proxy-e2e-azure-batches.yml
• Removed tests/proxy_e2e_azure_batches_tests/ directory (all test files, fixtures, mock servers)

No other tests or workflows referenced this directory, so no other CI jobs are affected.

Greptile Summary

This PR removes the consistently flaky proxy_e2e_azure_batches_tests CI workflow and its associated test directory, which were causing wasted CI minutes and developer friction without providing a reliable signal.

• Removes the proxy_e2e_azure_batches_tests job definition and its workflow trigger entry from .circleci/config.yml
• Deletes .github/workflows/test-proxy-e2e-azure-batches.yml (the GitHub Actions counterpart)
• Removes the entire tests/proxy_e2e_azure_batches_tests/ directory (~3,600 lines: base integration tests, conftest, mock Azure batch server, fixtures, E2E tests, and validation utilities)
• A search across the codebase confirms zero remaining references to the deleted directory or workflow — no orphaned imports or CI references remain

Confidence Score: 5/5

Safe to merge — pure deletion of a flaky CI workflow and its test directory with no impact on production code.

This is a straightforward infrastructure cleanup consisting entirely of deletions. No production or library code is touched, no other CI jobs reference the removed workflow or test directory (verified by codebase-wide search), and the CircleCI config correctly retains all other workflow triggers. There are no P0 or P1 findings.

No files require special attention.

Important Files Changed

Filename	Overview
.circleci/config.yml	Removes the proxy_e2e_azure_batches_tests job definition (~114 lines) and its workflow trigger; all other CircleCI jobs are untouched
.github/workflows/test-proxy-e2e-azure-batches.yml	Entire GitHub Actions workflow file deleted; was the GHA counterpart running the same flaky E2E suite
tests/proxy_e2e_azure_batches_tests/test_proxy_e2e_azure_batches.py	Deleted primary E2E test file (~324 lines) exclusively used by the removed CI workflow
tests/proxy_e2e_azure_batches_tests/test_managed_files_base.py	Largest deleted file (~1,085 lines) containing base-class tests for managed file operations in the Azure batch suite
tests/proxy_e2e_azure_batches_tests/fixtures/mock_azure_batch_server/mock_azure_batch.py	Deleted mock server implementation (~517 lines) simulating Azure Batch API responses; no longer needed
