Reinstate integration tests skipped in #611 to surface current failure state

[nathantournant]

Summary

PR #611 added @pytest.mark.skip override stubs for 12 integration tests, citing two broken test-org fixtures:

• The S3 destination bucket for the logs-archives fixture was deleted.
• The metric-tag-configurations fixture set on the test org is empty.

This PR removes those skip-override stubs (deletes the override methods so the tests fall back to the inherited BaseResourcesTestClass implementations of the same name), reinstating:

• tests/integration/resources/test_logs_archives.py: test_resource_sync, test_resource_sync_per_file, test_resource_update_sync, test_resource_update_sync_per_file, test_resource_cleanup, test_no_resource_diffs
• tests/integration/resources/test_logs_archives_order.py: test_resource_sync, test_resource_sync_per_file
• tests/integration/resources/test_metric_tag_configurations.py: test_resource_import, test_resource_import_per_file, test_resource_cleanup, test_no_resource_diffs

This PR is intentionally expected to fail CI. It is not meant to be merged as-is. Its purpose is diagnostic: to get a fresh, concrete, dated read on the actual current state of:

1. the logs-archives S3 destination bucket fixture, and
2. the metric-tag-configurations fixture on the test org,

and to convert the vague "fixture drift" explanation from #611 into an actionable, checkable state (either the tests still fail with the documented error, confirming the fixtures need re-provisioning, or they unexpectedly pass, meaning #611's skips can be reverted for real).

Related to #611.

Test plan

• Observe CI results on this PR (or run integration tests manually) for the logs-archives and metric-tag-configurations jobs.
• Confirm whether the S3 bucket / metric-tag-configurations fixtures are broken as described in test: skip 8 integration tests broken by test-org fixture drift #611, or have since been fixed.
• Based on the result, either re-provision the fixtures and keep the tests unskipped, or restore the skips in test: skip 8 integration tests broken by test-org fixture drift #611 with an updated/accurate reason.

Findings on the two broken fixtures

I dug through the test source and the recorded VCR cassettes (tests/integration/resources/cassettes/) to pin down concrete identifiers. CI hasn't produced a fresh failure log yet for this PR — the Run Integrations Tests workflow is currently queued behind another in-flight run (this repo's integration-test workflow uses a single global concurrency group, cancel-in-progress: false, so runs queue rather than run in parallel) — so the below is derived from cassette/config data, not a live failure trace. I'll follow up once a run actually executes.

1. logs-archives S3 destination bucket

From the recorded cassettes for test_logs_archives / test_logs_archives_order (e.g. TestLogsArchivesResources.test_resource_sync.yaml), the archive's destination config is:

"destination": {
  "bucket": "hamr-logs-archive-for-internal-testing",
  "path": "/logs-archive-testing",
  "type": "s3",
  "encryption": {"type": "NO_OVERRIDE"},
  "storage_class": "STANDARD",
  "integration": {
    "role_name": "datadog-aws-integration-role",
    "account_id": "267727855951"
  }
}

The sync flow reads the archive from the source org (api.datadoghq.eu, i.e. DD_SOURCE_API_URL) and re-creates it against the destination org (api.us5.datadoghq.com, i.e. DD_DESTINATION_API_URL). The recorded source archive's state was already "FAILING" at capture time, consistent with the bucket having since been deleted.

What needs to be (re)provisioned, as concretely as this repo shows it:

• An S3 bucket literally named hamr-logs-archive-for-internal-testing, in the AWS account 267727855951, with the archive path /logs-archive-testing.
• The AWS integration role datadog-aws-integration-role needs to exist in that account and be attached as the Datadog AWS integration (the archive references it by role_name + account_id, not raw credentials), with whatever bucket policy Datadog's log-archive S3 destination requires (s3:PutObject/s3:GetBucketLocation/etc. for the Datadog log-archiving principal).
• Once the bucket + role exist again, the destination org's logs_archives config should be re-pointed at it (or simply let datadog-sync sync recreate it, since the destination side is created fresh by the sync itself).

I could not find any indication in the repo of who owns/owned that AWS account or bucket, or a Terraform/CloudFormation definition for it — this looks like infra that lived outside this repo. If a live run does fail, the next diagnostic step is to pull the actual POST .../logs/config/archives response body from the CI log (gh run view <run-id> --log-failed) to get the exact API error (e.g. a 400 with a message naming the bucket/role) — I did not yet have a fresh failing run to pull that from.

2. metric-tag-configurations fixture

BaseResourcesTestClass.test_resource_import (in tests/integration/helpers.py) asserts len(source_resources) > 0 after importing — i.e. it requires the source org (DD_SOURCE_API_URL, the EU org) to have at least one metric with a tag configuration (manage_tags) already set. No filter is set on TestMetricConfigurationResources, so any configured metric satisfies the test — this isn't about one specific metric name being required by the test logic itself.

That said, the recorded cassette (TestMetricConfigurationResources.test_resource_import.yaml) shows what was previously configured on the source org, for concreteness:

• msr.distribution — tags ["environment", "host"], type distribution, include_percentiles: true
• msr.histogram.95percentile, msr.histogram.avg, msr.histogram.count, msr.histogram.max, msr.histogram.median — each tagged ["action_type"], aggregation {"time": "sum", "space": "sum"}

What needs to be provisioned: on the source (EU) test org, create/restore a metric tag configuration for at least one metric (ideally re-create the ones above, e.g. msr.distribution with tags environment/host, or any of the msr.histogram.* metrics with tag action_type) via POST /api/v2/metrics/{metric_name}/tags (or the Datadog UI's "Manage Tags" on a metric). Any single configured metric will unblock test_resource_import/test_resource_import_per_file; test_resource_cleanup and test_no_resource_diffs depend transitively on a prior successful sync, so they should follow once the import/sync tests pass.

I did not find a script or fixture-seeding tool in this repo that provisions test-org metrics/tags automatically — this looks like it needs to be done manually against the test org (or the metric needs to naturally exist with tag configs from real traffic).

This PR is expected to fail CI as-is; the intent is to get a dated, concrete signal (rather than the vague "fixture drift" note in #611) on whether these two fixtures are still broken, so they can be actually fixed instead of the skip going stale.
