Port of the .NET A2AAgent_AsFunctionTools sample to Python. Resolves a remote A2A agent card, converts each skill to a FunctionTool via as_tool(), and registers them with a host agent using AzureOpenAIResponsesClient. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Pull request overview
Adds a Python sample demonstrating how to discover a remote A2A agent’s skills and expose each skill as a FunctionTool so a host AzureOpenAIResponsesClient agent can autonomously choose and invoke those skills.
Changes:
- Added
a2a_agent_as_function_tools.pysample that resolves an AgentCard, turns skills into tools, and runs a host agent. - Updated the A2A samples README with the new entry, required environment variables, and quick-start steps.

as_tool() only auto-sanitizes when name is omitted. Since we pass skill.name explicitly, we need to strip special characters ourselves. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
