When a Docker container with the same name already exists (e.g., from a previous crashed GNS3 session), Docker returns a 409 Conflict error when trying to create a new container with that name. This causes the project open operation to fail. This fix adds automatic cleanup of stale containers when encountering a name conflict: - Added DockerHttp409Error exception class - Updated http_query to detect 409 status codes - Modified create() to remove conflicting containers and retry Fixes the issue where opening a project fails with: "Docker has returned an error: 409 Conflict. The container name '/GNS3.xxx' is already in use by container 'xxx'"
