Zun Compute fails on protobuf

[Radosław Piliszek]

The error message is:

2022-07-27 07:31:36.771 7 CRITICAL zun [-] Unhandled error: TypeError: Descriptors cannot not be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
 1. Downgrade the protobuf package to 3.20.x or lower.
 2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

    Regenerate protobuf files

    tools/gen-criapi was used with the latest protobuf dependencies
    to generate compatible files. This makes Zun Compute work again
    with the current implementation of protobuf.

    In addition, fix two issues that causes gate failure.
