Add deploy-examples command

[EngHabu]

Summary

• Adds a flyte deploy-examples command that deploys bundled example workflows from the examples/ directory
• Supports --type to select which example folder to deploy (defaults to basics)
• Lazily imports example modules only when the command is invoked to avoid import overhead
• Inherits all standard deploy options (--project, --domain, --version, --dry-run, etc.)

Usage

  flyte deploy-examples                          # deploys examples/basics
  flyte deploy-examples --type genai             # deploys examples/genai                                                                                                                                  
  flyte deploy-examples --type ml --dry-run      # dry-run examples/ml

Details

• Loads example files individually via importlib.util.spec_from_file_location since examples are standalone scripts, not packages
• Gracefully handles examples that fail to load (e.g. missing optional deps) — use --ignore-load-errors to skip them
• Deduplicates environments by name across example files

Test plan

• flyte deploy-examples --help shows correct options
• flyte deploy-examples --type nonexistent shows available types
• flyte deploy-examples --ignore-load-errors --dry-run loads modules and reaches deploy phase
• flyte deploy-examples --type genai --ignore-load-errors --dry-run works with a non-default type

you can just say flyte deploy --all --recursive examples/genai . right?
