Replace manual slice membership loops with slices.Contains in the string
utility helper, HTTP retry-code handling, and LUKS flag lookup.

No behavior changes are intended, and HTTP status code tests have
been added to help guarantee this since no prior status-code-checking
tests were in the repo.

This correction comes from the go fix output that was being silenced
in the pipeline previously. The errant lines can be seen in the ./test
output on the build in the main branch:

Walkthrough

HTTP retry-code, LUKS flag, and string-slice membership checks now use Go’s slices.Contains. New tests cover HTTP retry behavior, and a release-note fragment describes the replacements.

Changes: Slice membership modernization

Layer / File(s)	Summary
Membership checks and HTTP tests internal/resource/http.go, internal/resource/http_test.go, internal/exec/stages/disks/luks.go, internal/util/str.go, docs/release-notes.d/slices-contains.change.md	The three membership checks now use slices.Contains. HTTP tests cover matching and non-matching retry codes, nil and empty lists, and status codes 499, 500, and 503. The release note describes the replacements.

Priority: Low

Estimated code review effort: 2 (Simple) | ~10 minutes

The change preserves existing membership behavior and the HTTP tests do not contain the previously reported incorrect assertion.

Full details: Title check

Explanation

The title "internal: use slices.Contains for membership checks" follows the required 'subsystem: lowercase description' format, uses imperative mood, lowercase after the colon, and no trailing period. It clearly summarizes the main change: manual slice membership loops are replaced with slices.Contains in the LUKS, HTTP retry, and string utility code.

Full details: Description check

Explanation

The description states that manual slice membership loops are replaced with slices.Contains in the string utility helper, HTTP retry-code handling, and LUKS flag lookup. It also explains that no behavior changes are intended, that HTTP status code tests were added, and that the change follows go fix output. This matches the changeset.

LGTM!

[angelcerveraroldan]

The TMT test should now be fixed. I think that a re-base is needed, then we can re-run the test.

[angelcerveraroldan]

LGTM

[cadejacobson]

@angelcerveraroldan I rebased off of main and this now passes all pipelines. Thank you! 😁

[angelcerveraroldan]

@cadejacobson The new release.d structure should probably land today or tomorrow. When it does land I will ping here so that we can rebase if needed and move the release note to match the new structure - happy to merge then.

Thanks for the PRs!

[angelcerveraroldan]

@cadejacobson The PR landed, would you be able to rebase and migrate to the new release-notes structure ?
