By default newly created data lake users will have their Assignments (i.e. access to the system) for 2 years.

This reverts commit 45721d1e4cf94a672218f8795784703631f2ce9e.

"application/octet-stream" whcih makes accessing object via ERP5-ish UI impossible.
The reason for this is that a call to _range_request_handler was always setting this "Content-Type" header.
This before switch to Zope4 remained unoticed. Fix now.

   Use proper way of configure Mixin on portal types

   This value isnt exported anymore

With nexedi/wendelin@3f887532 and nexedi/wendelin@b4c22280 we already removed numpy security duplications:
this code already exists in ERP5 (with nexedi/erp5@a254bf50).
But we still missed some code parts: https://lab.nexedi.com/nexedi/wendelin/blob/b4c222803027a2d0d0fae793a4f16d4bea85f87d/product/Wendelin/__init__.py#L49-52
(perhaps because they looked different between erp5 and wendelin).

Furthermore with nexedi/erp5@79fa584e the last
numpy parts which only existed in Wendelin were also migrated to ERP5,
which is why we can finally also remove this from Wendelin.

Now all numpy related RestrictedPython definitions can be found in
the ERP5 codebase and they are no longer distributed over both ERP5
and Wendelin.

self.publish() had a bug regarding status code for empty responses on
Zope2 and that bug was fixed in Zope4, this adjust the code to support
both versions.
