   Use Certificate Login for store login definitions

Pygolang installs import hooks for pytest and ipython, to add
exception-chaining support into them(*) _iff_ (if and only if) those
modules are actually used. This works via Importing[1] which
pre-installs artificial modules into sys.modules that catch
__getattribute__ and try to import corresponding module for real on
first access. Usually everything is fine.

But with pylint/astroid, if the checker code happens to run with those
LazyModules installed, and the checked code has `import sys` somewhere,
astroid eventually delves into processing sys, then sys.modules and
wants to represent that sys.modules dict as dict of constant. Then, when
e.g. sys.modules['_pytest'] is processed, corresponding module object is
checked for .__class__, which raises ImportError if pytest is not
actually available:

    ( https://erp5js.nexedi.net/#/test_result_module/20220127-129289AE2/33 )
    ...
    File ".../eggs/astroid-1.3.8-py2.7.egg/astroid/node_classes.py", line 553, in __init__
        for k, v in items.items()]
      File ".../eggs/astroid-1.3.8-py2.7.egg/astroid/node_classes.py", line 962, in const_factory
        return CONST_CLS[value.__class__](value)
      File ".../eggs/Importing-1.10-py2.7.egg/peak/util/imports.py", line 254, in __getattribute__
        _loadModule(self)
      File ".../eggs/Importing-1.10-py2.7.egg/peak/util/imports.py", line 222, in _loadModule
        reload(module)
    ImportError: No module named _pytest

-> Fix it by detecting those lazy modules and not letting them go through
normal const_factory not to crash.

  Allow the developer associate a Mixin on Business template level
without require to overwrite the portal type itself

  Include mixins can be done in the same way, allowed content types or
property sheets are set.

Only catch exceptions, we don't need a bare except here. In case of
exception, log the traceback instead of being silent.

Since https://github.com/zopefoundation/Zope/commit/2da2c2c28a8b21e78e8ef93aa17da926e3102c26
SERVER_PORT is assumed to be convertible to int.

The value of this port is not really supposed to be used because
TimerServer requests does not have a server (for example in CMFActivity
we recreate the initial request), so put a value of -1 to prevent
accidental use.
