Update percona/mongodb_exporter dependency

[dehaansa]

PR Description

Update the mongodb dependencies to get the update from aws-sdk to aws-sdk-v2 for #2936 . There may be a few new metrics, but appear to be no other user facing changes.

• CHANGELOG.md updated

Looking at the test failure it seems like this somehow changed the output ordering for the test 🤔

Well that's... very strange. I don't see any reason why that happened, I was able to reproduce it locally so I guess I'll keep digging.

🔍 Dependency Review

github.com/percona/mongodb_exporter v0.45.1-0.20250630080259-d761c954bba6 → v0.47.1 — ⚠️ Needs Review

Summary:

• No API-breaking changes were introduced between v0.45.x and v0.47.1 for the library surface typically used by embedding the exporter (e.g., creating an exporter with a config and registering collectors).
• Changes across these releases primarily add new optional functionality (notably PBM/backup-related metrics) and bug fixes.
• Your repository’s config/testdata for prometheus.exporter.mongodb did not require structural changes in this PR, which is consistent with a non-breaking bump.

What to check in your code:

• If you construct the exporter via code (as opposed to only using the Alloy component), verify the Exporter/Config types you use still compile unchanged. No changes are expected, but double-check if you reference:
  • Collector settings (e.g., enabling/disabling named collectors).
  • Diagnostic/cluster-level options.
• If you explicitly manage the list of enabled/disabled collectors, v0.46+ includes new optional backup/PBM-related collectors. These remain opt-in, but if you rely on a whitelist/blacklist, ensure naming matches current collector names.

Likely code changes required:

• None detected. Keep existing calls as-is. Example (illustrative) config construction remains valid:

- exp, err := exporter.New(exporter.Config{
-   URI:             cfg.MongoURI,
-   DirectConnect:   cfg.DirectConnect,
-   DiscoveringMode: cfg.DiscoveringMode,
-   // CollectorsEnabled / Disabled unchanged
- })
+ exp, err := exporter.New(exporter.Config{
+   URI:             cfg.MongoURI,
+   DirectConnect:   cfg.DirectConnect,
+   DiscoveringMode: cfg.DiscoveringMode,
+   // If you want new backup/PBM metrics, explicitly enable the relevant collector(s).
+   // Otherwise, leave as-is to preserve current behavior.
+ })

Why “Needs Review” (not “Safe”):

• New optional collectors were introduced (backup/PBM) and bring new transitive deps (minio-go, mongo-tools, percona-backup-mongodb). While not breaking, this can:
  • Increase binary size and transitive surface.
  • Change runtime behavior if you programmatically enable “collect all” or specific collectors by name.
  • Affect scrape cardinality if you opt into new collectors.

Evidence:

• Percona MongoDB Exporter Releases/Changelog (review v0.46.0, v0.47.0, v0.47.1 notes for features and fixes; no API breaks called out):
  • https://github.com/percona/mongodb_exporter/releases/tag/v0.46.0
  • https://github.com/percona/mongodb_exporter/releases/tag/v0.47.0
  • https://github.com/percona/mongodb_exporter/releases/tag/v0.47.1
• Presence of new indirect deps related to backup/PBM and object storage support:
  • github.com/minio/minio-go/v7
  • github.com/percona/percona-backup-mongodb
  • github.com/mongodb/mongo-tools

Action items:

• If you only use the Alloy prometheus.exporter.mongodb component and do not enable new collectors: no code changes are required.
• If you enable collectors programmatically or via config, review the collector names you pass and opt in to new functionality only if desired.

Notes

• Several indirect dependencies were added or updated (e.g., cel.dev/expr, cloud.google.com/go/storage, github.com/minio/minio-go/v7, github.com/rs/xid, github.com/spiffe/go-spiffe/v2, github.com/zeebo/errs). These are transitive and part of new optional exporter functionality; no direct code changes are indicated for this repository.
