QgsMessageLevel::None cannot be used in Python

[gacarrillor]

The docs mention a QgsMessageLevel::None (C++) or QgsMessageLevel.None (Python) value that cannot be accessed in Python.

If Python devs attempt to use the Qgis.None, they'll get this error:

>>> Qgis.None
Traceback (most recent call last):
  File "/usr/lib/python3.8/code.py", line 63, in runsource
    code = self.compile(source, filename, symbol)
  File "/usr/lib/python3.8/codeop.py", line 176, in __call__
    return _maybe_compile(self.compiler, source, filename, symbol)
  File "/usr/lib/python3.8/codeop.py", line 104, in _maybe_compile
    raise err1
  File "/usr/lib/python3.8/codeop.py", line 91, in _maybe_compile
    code1 = compiler(source + "\n", filename, symbol)
  File "/usr/lib/python3.8/codeop.py", line 141, in __call__
    codeob = compile(source, filename, symbol, self.flags, 1)
  File "<input>", line 1
    Qgis.None
         ^
SyntaxError: invalid syntax

The corresponding SIP file also mentions the value None.

To enable this reserved name in Python, could we think about options like Qgis._None / Qgis.none or something like that?
