Remove integration, smoke, and VPC-SC tests that hit live GCP backends from pure generated GAPIC client libraries, along with their per-module .cloud/ Terraform test configs, IT-only test resources/dependencies, and corresponding keep: entries in librarian.yaml.

Motivation

• Pure GAPIC template generation and GAX runtime behaviors (unary/streaming RPCs, pagination, LROs, retries, dynamic routing headers, HttpJson/gRPC transports, and OpenTelemetry tracing/metrics/structured logging) are already deterministically covered by java-showcase (following the same rationale as ci: optimize unit test CI runtime and rename bulk filter #14029 for unit tests).
• Out of 257 Librarian-managed libraries, ~235 pure GAPICs already had no live integration tests; the remaining legacy suites primarily exercised backend service quotas, shared CI project state, and ML inference outputs rather than client code, causing frequent CI flakes (e.g., chore(vision): remove flaky ITSystemTest.detectFacesGcsTest #14837) and long Terraform provisioning/test runtimes (GKE clusters, Memorystore Redis instances, etc.) during monorepo-wide Kokoro IT and GraalVM runs.
• GraalVM native-image testing (-Pnative) continues to run **/*ClientTest.java mock tests across generated modules.

Scope

• Removed live-GCP ITs (IT*.java, *SmokeTest.java, *VPCServiceControl*Test.java) across pure generated GAPIC modules (java-accessapproval, java-asset, java-compute's ITPaginationTest, java-container, java-dialogflow, java-dialogflow-cx, java-errorreporting, java-iam-admin, java-kms, java-monitoring, java-os-login, java-recommender, java-redis, java-scheduler, java-speech, java-talent, java-tasks, java-texttospeech, java-trace, java-video-intelligence, java-vision, java-websecurityscanner), along with .cloud/ Terraform configs for modules that no longer have ITs (including orphaned .cloud/ dirs in java-dataflow and java-secretmanager).
• Preserved all integration tests in handwritten and hybrid/combo libraries, plus Compute's golden signals e2e observability test:
  • Dedicated handwritten/combo modules (java-bigquery, java-bigquery-jdbc, java-bigquerystorage, java-bigtable, java-datastore, java-dns, java-firestore, java-logging, java-logging-logback, java-notification, java-pubsub, java-spanner, java-spanner-jdbc, java-storage, java-storage-nio, google-auth-library-java, grpc-gcp-java, java-showcase).
  • GAPIC_AUTO modules that still ship handwritten legacy wrappers or helpers (java-resourcemanager, java-translate, and java-containeranalysis's local ITGrafeasInteropTest).
  • java-compute's ITComputeGoldenSignals (and BaseTest / java-compute/.cloud).

Code Review

This pull request removes integration tests, smoke tests, VPC Service Control tests, and their associated Terraform configurations, helper scripts, and test dependencies across a large number of Google Cloud Java client modules. Additionally, it cleans up the corresponding pom.xml files and librarian.yaml to reflect these removals. As there are no review comments, I have no feedback to provide.
