feat(query)!: decide the tenant of every read by policy - #203

Conversation
* Breaking Changes * Refused Loki, Tempo and Flight SQL reads whose `x-scope-orgid` is malformed, duplicated or names a tenant a `single` deployment does not serve; these were previously served `default` or the named tenant's rows. * New Features * Added the query `tenant` policy: `single` (default, one tenant per deployment) or `multi` (tenant taken from `x-scope-orgid`, a request without it refused), set via `query.tenant` in Helm and `tenant` in Compose. * Added the `icegate_query_tenant_rejections` counter labelled by `protocol` and `reason`. * Switched the Compose stand, Kubernetes overlays and auth-proxy example to `multi`, with the bundled Grafana datasources sending `X-Scope-OrgID: demo`. * Bug Fixes * Fixed query pods being restarted when the Loki port is disabled: both probes now hit `/health` on the operational listener. * Refactor * Moved the gRPC tenant interceptor into `icegate-common`, so OTLP/gRPC and Flight SQL refuse the same request the same way. * Documentation * Documented the query tenant policy, its refusals per protocol and why `multi` must only be reachable by trusted callers.

In `@config/helm/icegate/values.yaml`:
- Around line 312-330: Keep `livenessProbe` on `/health`, and change
`readinessProbe` to use a readiness route that reports success only after all
enabled query listeners have bound. Locate the readiness handling alongside
`spawn_servers` and ensure the route tracks every enabled query listener before
returning success.

Grafana datasource provisioning deleteDatasources prune behavior existing datasource removed from provisioning file
💡 Result:
**Yes—`prune: true` is intended to delete a provisioned datasource when it’s no longer present in its provisioning file, or when that file is removed.** It must be at the YAML root of the datasource file. ([grafana.com](https://grafana.com/docs/grafana/latest/administration/provisioning/?pg=blog&plcmt=body-txt&utm_source=openai))
There’s an important two-restart detail:
1. Add `prune: true` to the file that provisions the datasource and restart Grafana. This marks the datasource as prunable.
2. Remove the datasource entry (or the file) and restart Grafana again. Grafana then deletes the datasource.
Adding `prune: true` only after removing the datasource may not delete it: Grafana needs to record the prunable flag first. (GitHub issue 94645 in grafana/grafana (link omitted to avoid creating a cross-reference))
For an explicit deletion instead, use `deleteDatasources` with the datasource’s `name` and `orgId`; Grafana processes those deletions before provisioning the `datasources` list. ([grafana.com](https://grafana.com/docs/grafana/latest/administration/provisioning/?pg=blog&plcmt=body-txt&utm_source=openai))

🌐 Web query:
site:grafana.com/docs/grafana/latest/administration/provisioning deleteDatasources name orgId datasource provisioning
💡 Result:
In Grafana datasource provisioning, `deleteDatasources` takes a list of data sources identified by **both `name` and `orgId`**. Grafana deletes those entries **before** processing the `datasources` list. ([grafana.com](https://grafana.com/docs/grafana/latest/administration/provisioning/?pg=blog&plcmt=body-txt&utm_source=openai))
```yaml
apiVersion: 1
deleteDatasources:
- name: Old Prometheus
orgId: 1
```
For automatic cleanup when a provisioned datasource is removed from the file, set root-level `prune: true` instead. ([grafana.com](https://grafana.com/docs/grafana/latest/administration/provisioning/?pg=blog&plcmt=body-txt&utm_source=openai))

Delete the removed Loki and Tempo datasources during provisioning.
When an existing Grafana database is retained, the new Loki (demo) and Tempo (demo) names do not replace the old Loki and Tempo records. Grafana can leave the old datasources selectable. Requests from them omit X-Scope-OrgID, so the multi query service rejects them.
Add these entries to both provisioning documents:
Suggested fix
apiVersion: 1
+deleteDatasources:
+ - name: Loki
+ orgId: 1
+ - name: Tempo
+ orgId: 1
+
datasources:Apply the same change to config/docker/grafana/provisioning/datasources/datasources.yaml and the datasources.yaml object in config/kustomize/base/values-grafana.yaml.
Use explicit deletion for this upgrade. Adding prune: true now may require a prior provisioning run to mark the old datasources as prunable.
