Alexsander Hamir 30b28da2b7 Add pyroscope for observability (#21167) ...

* Pyroscope: require PYROSCOPE_APP_NAME and PYROSCOPE_SERVER_ADDRESS, add UTF-8 locale hint

- No defaults for PYROSCOPE_APP_NAME or PYROSCOPE_SERVER_ADDRESS; fail at startup if unset when Pyroscope is enabled
- Set LANG/LC_ALL to C.UTF-8 when unset to reduce malformed_profile (invalid UTF-8) rejections
- Startup message suggests PYTHONUTF8=1 if server rejects profiles
- Simplify LITELLM_ENABLE_PYROSCOPE in config_settings; document Pyroscope env vars as required with no default
- Add pyroscope_profiling to sidebar (Alerting & Monitoring)
- pyproject.toml: pyroscope-io as required dep on non-Windows (marker), in proxy extra

* proxy: add PYROSCOPE_SAMPLE_RATE env, use verbose logging, fix int type

- Add optional PYROSCOPE_SAMPLE_RATE env (integer, no default)
- Pass sample_rate to pyroscope.configure() as int for pyroscope-io
- Replace print with verbose_proxy_logger (info/warning)
- Document PYROSCOPE_SAMPLE_RATE in config_settings.md

* Address Greptile PR feedback: Pyroscope optional, docs, tests, docstring

- pyproject.toml: mark pyroscope-io as optional=true (proxy extra only)
- Add docs/my-website/docs/proxy/pyroscope_profiling.md (fix broken sidebar link)
- Add tests/test_litellm/proxy/test_pyroscope.py for _init_pyroscope()
- proxy_server: fix _init_pyroscope docstring (required server/app name, sample rate as int)

* Update litellm/proxy/proxy_server.py
