Supports the case where Products.DCWorkflowGraph is not present.
Even though we are removing Products.DCWorkflowGraph from the
software release, we don't remove this monkey patch yet, because
this monkey patch also fixed a severe security issue. We keep the
patch for the cases where a recent ERP5 runs on an old SlapOS where
the product is still there.

This change just moves the existing code in a try/except ImportError
block

See merge request !1615

Rationale:

Converting * to data frame / numpy array efficiently is required in all
wendelin projects, without this functionality wendelin is useless.
Currently all projects allow this functionality in an insecure way.
This commit aims to improve the situation by supporting a secure way of
this functionality.

(See nexedi/wendelin!99 (comment 158474))

Because pandas (in restricted Python) can also be useful in 'pure' ERP5
(without Wendelin) the functionality is added to ERP5 source code.

---

Security:

Security is guaranteed by patching selected read_* functions and
allowing the patched versions. The patch prohibits anything but
string input which directly contains the data (e.g. no urls, file
paths). New unit tests ensure the restrictions of the patches
are actually effective.

---

Notes on implementation decisions:

Instead of offering new ERP5 extension methods (e.g. Base_readJson)
this commit adds patched pandas read functions in restricted Python.
In this way the change of the known API is as minimal as possible.

Instead of globally monkey-patching pandas read_* functions, only the
functions inside restricted python are patched.
In this way the fully-functional, original functions are still available
in Zope products or ERP5 extension code.

Minor changes in the way how pandas is allowed in restricted python
have been applied. Please consult the following discussions in the Merge

Translated property accessor accessor accidentally changed to return
on python2 unicode for translated messages and str for non translated
messages in a17bb910 

To make it worse, CMFCategory's Renderer was swallowing exceptions.

This restores translated accessors behavior and changes Renderer to
let exceptions propagate

See merge request nexedi/erp5!1629

partially revert a17bb910 (py2/py3: Make Products code compatible
with both python2 and python3., 2022-04-13) so that
TranslatedPropertyGetter keeps returning utf-8 encoded str (bytes) on
python2 and returns text only on python3.

This regression caused displaying categories to raise unicode error or
to silently not display the labels for.

This just hides issues.

In commit a17bb910 ("py2/py3:
Make Products code compatible with both python2 and python3"),
2to3 changed `_.has_key(...)` to `... in _` whereas _ is not a dict.

This is for *StandaloneDeploymentScriptTest* test suites, which
download a large disk image during slapos node instance step.

For example, on a Wendelin.StandaloneDeploymentScriptTest-Debian.Stretch
test run [1], we can see that the slapos node instance started at
2022-05-13 07:50:30,788 and stopped trying at 2022-05-13 07:51:35,885.

In the last run, slapos node instance failed, especially this promise:

    2022-05-13 07:51:35,701 INFO     slapgrid_cp: 2022-05-13 07:51:35 slapos[3548917] ERROR ERROR '/srv/slapgrid/slappart22/t/cjl/i/1/srv/monitor/private/virtual-hard-drive-url/virtual-hard-drive-url-processed-config.state' not empty, content available at https://[???]:8026/private/virtual-hard-drive-url/virtual-hard-drive-url-processed-config.state
    ...

and if we access this URL, we can see the error:

    [Errno 2] No such file or directory: '/srv/slapgrid/slappart22/t/cjl/i/1/var/virtual-hard-drive-url/update-image-processed.md5sum'

which means that the image is still not downloaded.

testnode still ignore slapos node instance state return code and run
tests anyway, so the test ran and failed later.

This image is 1.8Go, when I tried to download it locally it took
56.41 seconds, so it must be generally almost OK.

By retrying up to 60 times, we give more time for the slapos node
instance step to download the image.

Revert "py3: sortKey() must be a string as comparison between str and None/int/tuple now raises TypeError."

This reverts commit 192c2000.

This commit introduced a test failure with testCommitOrder
testInvalidationBug.TestInvalidationBug [1]

    Traceback (most recent call last):
      File "Products/ERP5/tests/testInvalidationBug.py", line 93, in testCommitOrder

That commit was apparently in the good direction, because transaction
API specifies that sortKey must return string

This allows executing a script doing REQUEST.RESPONSE.redirect() without
error.

Before this patch it's an AttributeError similar to:

    Traceback (most recent call last):

    AttributeError: TimerResponse instance has no attribute 'redirect'

Instead of temporarily changing the global timeout, which can impact
other parts of the system and which is not free from race conditions (
another thread might have changed the timeout when socket.getdefaulttimeout()
is called and then we restore a wrong default timeout).
