context consistency: ensure all context are TODO()

[sebrandon1]

There were 14 instances of context.Background and 20 instances of context.TODO(). Since there were more TODO() references, I'm ensuring all of the references to context are the same.

Hi @sebrandon1. Thanks for your PR.

I'm waiting for a openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Hi @sebrandon1, you may need to rebase onto the latesr commit. There have been some changes in test/e2e folder since you opened this PR

Walkthrough

Replaces many uses of context.Background() with context.TODO() across controllers, tests, and utilities; updates an example comment; and adds a new end-to-end test file introducing multiple cert-related E2E tests and helpers. No exported/public signatures altered.

Changes

Cohort / File(s)	Summary
Controller & tests: context switch pkg/controller/istiocsr/controller.go, pkg/controller/istiocsr/controller_test.go, pkg/controller/istiocsr/test_utils.go, pkg/controller/deployment/deployment_helper_test.go	Replaced context.Background() with context.TODO() in reconciler init, Reconcile calls, test constructors, and related tests.
E2E tests: context adjustments test/e2e/certificates_test.go, test/e2e/overrides_test.go	Switched test setup/context arguments from context.Background() to context.TODO(); behavior unchanged.
Test utilities: namespace lifecycle test/library/utils.go	Updated Namespace create/delete and polling calls to use context.TODO() instead of context.Background().
Operator informers: docs example pkg/operator/informers/externalversions/factory.go	Comment/example updated to show context.TODO() instead of context.Background(); no code changes.
New E2E suite: cert-manager deployment & flows test/e2e/cert_manager_deployment_test.go	Added new end-to-end test file with constants (PollInterval, TestTimeout) and tests: TestSelfSignedCerts, TestACMECertsIngress, TestCertRenew, TestContainerOverrides, plus helpers for deployment overrides, polling, and TLS/expiry verification.

❌ Failed checks (1 warning)

Check name	Status	Explanation	Resolution
Docstring Coverage	⚠️ Warning	Docstring coverage is 7.14% which is insufficient. The required threshold is 80.00%.	You can run @coderabbitai generate docstrings to improve docstring coverage.

✅ Passed checks (2 passed)

Check name	Status	Explanation
Title Check	✅ Passed	The pull request title "context consistency: ensure all context are TODO()" directly and specifically describes the main change across the changeset. The raw summary shows that the primary objective is standardizing context usage from context.Background() to context.TODO() across multiple files in the codebase. The title is concise, clear, and specific enough that a teammate scanning the history would immediately understand the primary change being made. Although the changeset includes a new e2e test file, the dominant change throughout the PR is the context standardization.
Description Check	✅ Passed	The pull request description is clearly related to the changeset. It explains the concrete rationale for the changes—14 instances of context.Background() versus 20 instances of context.TODO(), with the author choosing to standardize on the more frequently used TODO()—and provides references to similar prior work in related repositories. The description conveys meaningful information about why the changes were made and demonstrates precedent for this type of consistency effort. It is not vague, generic, or off-topic.
