Add support for perspective 3

[timkpaine]

Was able to workaround the below OOTB issue.

---

looks like an issue with perspective and cloudpickle

(ServeController pid=48713)   File "/opt/homebrew/Cellar/python@3.11/3.11.10/Frameworks/Python.framework/Versions/3.11/lib/python3.11/concurrent/futures/_base.py", line 456, in result
(ServeController pid=48713)     return self.__get_result()
(ServeController pid=48713)            ^^^^^^^^^^^^^^^^^^^

(ServeController pid=48713)     deployment_def = cloudpickle.loads(serialized_deployment_def)
(ServeController pid=48713)                      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
(ServeController pid=48713) AttributeError: type object 'PySyncServer' has no attribute 'new_session'

I believe this is due to global state in perspective>=3.
