feat(agent-data-plane): added support for topology visualization

[lucastemb]

Summary

In its current state, Saluki, and subsequently, Agent Data Plane, has no method to reliably visualize topologies. This PR introduces a tool that utilizes *.yaml config files to generate visual aids.

Features:

• Render topology output in two formats:
  • Mermaid (.mmd): supported natively by Github, can be embedded into PR descriptions to render diagrams.
  • JSON: produces output that the TypeScript and Vue-based visualizer tool leverages to render an interactive tool (this logic exists in a separate repository).
• Compute the difference between topologies produced by two different configs
• Visualizer available at localhost:5173/topology
  • Filter by component type and edge type
  • Change orientation (top-down, left-right)
  • Click on component to view detailed description of component function
    • Utilizes Rust doc page to deliver information
    • Descriptions only updated if a commit on the user's current branch has modified files in specific directories
  • Highlight node's upstream and downstream path

Change Type

• Bug fix
• New feature
