Add Semantic Kernel as orchestrator

[cecheta]

Closes #758

Purpose

• This PR adds Semantic Kernel as a third orchestration choice
  • Semantic Kernel is being used as a wrapper around OpenAI functions, therefore users should see no difference between using OpenAI Functions or Semantic Kernel (Question: Could semantic_kernel replace openai_function?)
  • Semantic Kernel uses plugins with functions to call the tools, as well as run the post-answering prompt
• Moves calling content safety into OrchestratorBase to reduce duplication
• Fixes TextProcessingTool to use the inputs coming from the LLM
• Fixes bug where app doesn't work with RBAC
• Fixes some typing errors
• Updates tests

Does this introduce a breaking change?

[ ] Yes

really happy with the direction - going to deploy and have a play! Let me know if you want me to involve the SK team

nit: When I chose semantic_kernel in the Configuration page, it succesfully saves the config in storage, but the UI (drop down) does not show that I am on semantic kernel

Accidentally closed this - sorry!
