How to do end-to-end messagecrypto with Python client

[jiazhai]

in issue #6834, user report there is no doc for configure and use feature end-to-end messagecrypto in python.
We need to confirm whether this feature is supported in python, and add needed doc.

@jiazhai , whether end-to-end messagecrypto is supported on Python?

[devdattakulkarni]

@jiazhai We are also interested in this. Do you know if this is already supported and just the documentation is missing, or if this feature is yet to be supported in the Python client?

Here is a test that shows how to use e2e encryption: https://github.com/apache/pulsar-client-python/blob/9182dd7ab69266ad0fb630a129a3ef478c1f8ab0/tests/pulsar_test.py#L369

@BewareMyPower Thank you! I'll convert this thread to a Q&A and select the answer.

Further improvement to add the example to https://pulsar.apache.org/docs/client-libraries-python or elsewhere is possible.
