KUBE-169: Simplify shared MongoDB Search query snippets

[anandsyncs]

Summary

Simplifies the shared replica-set and sharded MongoDB Search query snippets while keeping public commands customer-friendly.

• Keeps readiness polling internal to CI.
• Replaces the fixed wait with a public index-status check.
• Preserves published scenario 03 filenames.
• Keeps CI-only non-empty-result assertions out of public snippets.

Jira: KUBE-169

Stack: 1/3. Followed by the replica-set and sharded multi-cluster Search snippet PRs.

Extracted from #1368.

Evergreen proof

Full-stack Search snippets patch passed all nine Search snippet tasks: seven single-cluster and two multi-cluster.

MCK 1.10.0 Release Notes

New Features

• MongoDBOpsManager, AppDB: The mongodb-agent-monitoring sidecar container has been merged into the main
  mongodb-agent container. Both automation and monitoring now run as a single process in a single container. The
  spec.appDB.monitoringAgent field is now deprecated and has no effect; Monitoring Agent options for the AppDB —
  including log level and rotation — are configured via spec.applicationDatabase.agent and
  spec.applicationDatabase.agent.monitoringAgent, the same fields used by MongoDB resources. Enabling AppDB
  monitoring still results in rolling restarts of AppDB pods.
• MongoDBSearch: Added support to show cluster level status of Search, Managed LoadBalancer and MetricsForwarder in the MongoDBSearch resource's status.clusters field.
• MongoDBSearch: Added support to configure the node affinity of the MongoDB Search (mongot) pods using the MongoDBSearch CR fields spec.clusters[].nodeAffinity or spec.clusters[].shardOverrides[].nodeAffinity.

Bug Fixes

• MongoDBUser: Fixed a bug where the connection string Secret created in the central cluster did not carry a controller owner reference to the MongoDBUser CR. The missing reference prevented Kubernetes garbage collection from cleaning up the Secret when the MongoDBUser was deleted.
• MongoDBUser: Fixed a bug where the ownership guard on the connection string Secret was always satisfied regardless of the actual owner, allowing the operator to silently overwrite a Secret controlled by a different resource.
• Fixed a bug where all MongoDBCommunity deployment telemetry rows incorrectly reported IsRunningEnterpriseImage = true. The field was being evaluated against the operator-level enterprise image rather than the image configured in each CR's spec, causing a misleading ~100% enterprise rate for the Community deployment type.
• IsRunningEnterpriseImage for Community deployments is now derived from the mongod container image override in spec.statefulSet.spec.template.spec.containers, if present. When no override is set, the field correctly defaults to false, reflecting that Community CRs use the community MongoDB server image by default.
• MongoDBOpsManager, AppDB: Fix for spec.applicationDatabase.agent.monitoringAgent.logRotate field not being
  handled properly. Additionally, added defaults for
  spec.applicationDatabase.agent.monitoringAgent.logRotate.sizeThresholdMB to 1000 and
  spec.applicationDatabase.agent.monitoringAgent.logRotate.timeThresholdHrs to 24, which are same defaults Ops Manager
  would set.
• MongoDBSearch: The default JVM heap size (half of the memory request) is now capped at 30GB, following the mongot sizing guidance. Heap sizes above ~30GB prevent the JVM from using compressed object pointers and degrade performance. User-provided heap flags are not affected, if more than 30GB heap is required, we recommend using jvmFlags.

Pull request overview

This PR simplifies the shared MongoDB Search query-usage snippet modules (replica set + sharded) by separating CI-only readiness behavior from customer-facing steps and by making the “wait” step a public index-status inspection rather than a fixed sleep.

Changes:

• Updates the sharded query-usage harness to run an internal readiness poll and then a public getSearchIndexes() status check.
• Refactors query snippets to execute mongosh directly via kubectl exec heredocs (removing the intermediate “write JS to /tmp” pattern).
• Adds/updates READMEs to make scenario handoff and quick-run instructions clearer for single- and multi-cluster flows.
