.Net: Plugins at scale

[markwallace-microsoft]

Provide samples and guidelines on how to use multiple plugins:

• Fixes for known reliability issues e.g., hallucinated function names
• Add the ability to change functions being advertised dynamically based on current context
  • Works with M.E.AI
• Learn site documentation and samples showing how to manage a large set of plugins/functions
• https://learn.microsoft.com/en-us/semantic-kernel/frameworks/agent/agent-contextual-function-selection?pivots=programming-language-csharp
• https://devblogs.microsoft.com/semantic-kernel/smarter-sk-agents-with-contextual-function-selection/
  - [ ] Samples/tests showing how to evaluate how a new model behaves
  - [ ] Initial task is to create an ADR describing the approach

Consider changing this to be a multi-agent sample where each agent has a limited set of functions and the correct agent is selected.
