Pull request overview

This PR reworks the azure-ai-projects hosted-agent samples so they no longer depend on RBAC role assignment. RBAC support (rbac_util.py, ensure_agent_identity_rbac[_async]) is removed, and the image/code/session samples now consistently create a version, route the agent endpoint to it via update_details, exercise it, and then tear down (restore the original endpoint and delete the version). The old echo-agent asset is replaced with basic-agent, the zip helper is renamed to zip_directory, and shared create_version_from_code[_async] context managers centralize the create/wait/route/teardown lifecycle. Sample renames (sample_create_hosted_agent[_async].py → ..._from_image[_async].py) and the removal of sample_agent_endpoint[_async].py are reflected in the sample-test parametrization.

Changes:

• Remove RBAC assignment path and the echo-agent container asset; standardize samples on create_version_from_code[_async] + update_details + endpoint restore + version delete.
• Rename zip → zip_directory and the select_echo_agent_code_zip helper → select_basic_agent_code_zip; add shared lifecycle context managers.
• Update sample-test discovery/parametrization (new session/log-stream entries, renamed image samples) and add a _resolve_sample_path_from_filename fallback in sample_executor.py.

File	Description
samples/hosted_agents/hosted_agents_util.py	Adds create_version_from_code[_async] context managers; renames helper to select_basic_agent_code_zip; drops get_latest_active_agent_version[_async].
samples/hosted_agents/sample_create_hosted_agent_from_image.py	Renamed from sample_create_hosted_agent.py; RBAC replaced with endpoint routing (stale RBAC/echo-agent docstrings remain; no teardown).
samples/hosted_agents/sample_create_hosted_agent_from_image_async.py	New async image sample with endpoint routing + teardown (stale echo-agent ref and unneeded mgmt deps in docstring).
samples/hosted_agents/sample_create_hosted_agent_from_code[_async].py	Switch to basic-agent, hardcode agent name, add endpoint routing + teardown.
samples/hosted_agents/sample_sessions_crud[_async].py, sample_sessions_files_upload_download[_async].py, sample_session_log_stream[_async].py	Create a temporary version via the new context manager instead of resolving an existing active version.
samples/hosted_agents/sample_toolbox_with_skill.py, sample_agent_user_identity_isolation.py	Use create_version_from_code; remove RBAC and inline lifecycle handling.
samples/hosted_agents/rbac_util.py, sample_agent_endpoint[_async].py, sample_create_hosted_agent_async.py, assets/echo-agent/*	Deleted.
samples/hosted_agents/assets/Dockerfile	New Dockerfile for building an agent image.
samples/util.py, samples/skills/sample_skills_upload_and_download[_async].py	zip → zip_directory rename and callers updated.
tests/samples/test_samples.py, test_samples_async.py, sample_executor.py, test_util.py	Update sample-test parametrization/skip lists and add synthetic-path fallback logic.

sdk/ai/azure-ai-projects/samples/hosted_agents/sample_create_hosted_agent_from_image.py:15

• This docstring still claims the sample sets up agent identity RBAC via ensure_agent_identity_rbac, but RBAC was removed from this sample in this PR (the rbac_util import and the ensure_agent_identity_rbac call are gone, and rbac_util.py is deleted). The statement is now inaccurate and should be updated to reflect that the sample routes the agent endpoint via update_details.
  sdk/ai/azure-ai-projects/samples/hosted_agents/sample_create_hosted_agent_from_image.py:30
• This references the assets/echo-agent folder, which is deleted in this PR (its main.py, README.md, and requirements.txt are removed). The replacement asset is assets/basic-agent (a new assets/Dockerfile is also added). Please update the reference so users aren't pointed at a nonexistent folder.
  sdk/ai/azure-ai-projects/samples/hosted_agents/sample_create_hosted_agent_from_image.py:93
• Unlike its async counterpart sample_create_hosted_agent_from_image_async.py (which captures original_agent_endpoint, restores it, and deletes the created version in a finally block), this sync sample configures the endpoint via update_details but never restores the original endpoint or deletes the created version. This diverges from the PR's stated goal of "tear down by restore back the agent detail and delete hosted agent" and, on repeated runs, leaves the agent endpoint pointed at a version and accumulates undeleted versions. Consider wrapping the body in try/finally with endpoint restore and version cleanup to match the async variant.
