Fix report generation for url endpoints (#876)

Earlier, we would have some unknown magic to identify the path for
remote endpoints when testing client_sdk/tests.
Removed that and now you have to explicitly pass a path

+## Report Generation
+
+To generate a report, run with `--report` option
+```bash
+LLAMA_STACK_CONFIG=together pytest -s -v report.md tests/client-sdk/ --report
+```
 
 ## Common options
 Depending on the API, there are custom options enabled
 - For tests in `inference/` and `agents/, we support `--inference-model` (to be used in text inference tests) and `--vision-inference-model` (only used in image inference tests) overrides
 - For tests in `vector_io/`, we support `--embedding-model` override
 - For tests in `safety/`, we support `--safety-shield` override
+- The param can be `--report` or `--report <path>`
+If path is not provided, we do a best effort to infer based on the config / template name. For url endpoints, path is required.
