[Feature] Helm Charts for Txt2Img and SearchQnA.

Any priority list for the GenAIExamples? If we don't have enough resource to add all examples, we need priority list to decide which to go first.
Besides adding more Examples, I think the most important thing to do is fix issues and enhance the high priority Examples/Components to make them ready for production.

Hi @yongfengdu, is your team working on this?

[yongfengdu]

As I know the GenAIExamples is under refactoring for 1.2, and helm-chart will need to change accordingly.
It's not wise to add more examples if they will be merged soon.
I'd propose to postpone the "more examples support" to 1.3 release, since it would be a waste of engineering resource if we're doing sth like this:
#590 - Add more microservices for docsum
#659 - Reduce microservices in docsum

The later one removed >80% of the code for previous PR.

Walked through the GenAIExamples' current list, here is the summary for gaps:

• Already supported, will follow up with update
  AgentQnA, AudioQnA, ChatQnA, CodeGen, CodeTrans, DocSum, FaqGen, VisualQnA

• Not yet supported, but is planning to do (5 Examples).
  AvatarChatBot - AudioQnA+wav2lip+animation, 2 more microservices required.
  DBQnA - Use LLM to Generate SQL. CPU only. More components required postpres, text2sql-service
  GraphRAG - Variants of ChatQnA, neo4j graph database required, Gaudi only
  SearchQnA - Use webretriever. Web-retriever supported, CPU only
  Text2Image - No compose file, Components only

• Not support. no plan to support.
  DocIndexRetriever - Not an E2E example, part of AgentQnA
  EdgeCraftRag - ARC GPU only, all functions are implemented in edgecraftrag-server, not using GenAIComps. Less likely to run on k8s environmetn, defer the support or more discuss/requirement needed.
  InstructionTuning/RerankingTuning - Not E2E example, No compose file
  MultimodalQnA - To be merged with VisualQnA
  ProductivitySuite - To be merged with ERAG
  Translation - To be merged with CodeTrans
  VideoQnA - To be merged with VisualQnA

While EdgeCraftRag may not be important, I think Intel GPU support is important.

(Gaudi is too expensive for normal devs, so if Intel GPU support is not available, some other manufacturer's GPUs are used for acceleration, and that dev is lost for Intel.)

FYI: there's old open PR for adding vLLM OpenVINO / GPU support for ChatQnA: #403

To be added to a list. Helm chart for vLLM support for DocSum service is required.

To be added to a list. Helm chart for vLLM support for DocSum service is required.

That was merged few hours ago: #649

ChatQnA vLLM support was merged last month: #610

However, currently ChatQnA uses vLLM only for LLM. Embedding, reranking, and guardrails still uses TEI / TGI. There was PR to add vLLM embedding support, but review had comment that it might not be needed: opea-project/GenAIExamples#1237

And Helm charts for all other applications are lacking vLLM support.
