primary-site: rename stream server to query service

[james-rms]

Changelog

• The stream-server container image has been renamed to query-server. New images will no longer be published under the stream-server name.
• the streamService values namespace has been renamed to queryService. Values defined in the legacy streamService namespace will continue to work. streamService values override default values defined in the queryService namespace before templating.
• breaking The stream-service application and deployment are removed, and replaced with an query-service deployment. Any auto-scaler which uses the stream-service deployment name as a scaleTargetRef will no longer have any effect. To upgrade safely:
  • Add a new autoscaler that targets the query-service deployment.
  • Upgrade and test your deployment.
  • Schedule a date in the future to remove the old autoscaler. After removing the old autoscaler, this chart should not be rolled back past this version.
• The stream Kubernetes service is renamed to query.

I think we should leave stream service to maintain compatibility, but otherwise 👍
