Don't log and fix a few resource warnings

See merge request nexedi/erp5!1307

Add missing field, used in testFloatFieldStep

It follows commit ce233f79

Some fields may use div element without expecting 100% width.
Example: formbox and diff gadget.

this prevents ResourceWarnings on python3

this prevent ResourceWarnings on python3

this is way to verbose and not really useful

Why invent a different way, making it harder to consistently patch
validated_hook ?

For example, allows upgrading a Business Template when an ERP5 Form is
replaced by a PythonScript in a skin folder.

When running on testnode, runUniTest is responsible for picking a free $DISPLAY.
This is implemented by starting Xvfb on a $DISPLAY, waiting a bit and if it is
still running we assume the $DISPLAY was free. But it seems sometimes we don't
wait enough, when testnodes are overloaded.

This implementation is wrong, we could run a command check that X is running,
but as explained in the code command below, xdpyinfo or other tools are
currently not available in test environment. Since we are considering switching
this to seleniumserver (which would take care of running a X Server for us) so
this is OK for now.

there was also another script for internal

This test was clicking on the first item in a non sorted list and then
checking that the text of the selected element was "a2".

Instead, store the text of the first listbox cell in a variable and use
this in check.

Implement related keys for translated relations (like `source__translated__title`) and change content translation to index categories, by also indexing types whose translation is set in Localizer.

Changing the language and browsing to another web section require to fully refresh the page.

Now that we are able to search using content translation, we also want
to extend this so that columns like "group__title" can be searchable in listboxs,
but categories are usually translated with `erp5_content`, which was not indexed
in content_translation table.

Extend content translation indexing to also support translations coming from
Localizer catalog make this possible.

The only limitation I could think of is that categories will need to be reindexed
when the messages are modified in catalog.

Translated properties are indexed in content translation table,
so nothing prevent us from using them in related keys. Since in
many places we show to user translated titles in relations, it
makes sense to also support searching and sorting in catalog.

This extends related keys syntax only for the newest syntax, so
related keys like `source__translated__title=X` would allow searching
for document who have a source relation to a document with title X.

Since any properties can be translated, if for example a property
`foo` would exist and be translatable, it would be possible to search
using `source__translated__foo=X`

This is only available when content_translation business template
is installed.

The default value of the field was calling Base_getEditorFieldPreferredTextEditor and returned the preferred text editor, because this script assumes the content type to be text/html by default

Ever since the introduction of X-Balancer-Current-Server in SlapOS
haproxy configuration in:
  commit c7f104fbf1f5948928f5545286afbb94fc39102b

      erp5_cluster: leave ERP5 set the haproxy cookie

the balancer will overwrite this cookie's value, so do not compare it
to our name: balancer may be calling us a name completely unrelated to
the value getCurrentNode returns.
So simplify this function's logic to only do what the docstring says:
decide when to set and when to unset the balancer cookie, and let the
balancer decide the value.
This resolves cases where Zope would set the cookie over and over on
every request when getCurrentNode and balancer disagree on its value.

- use environment variables to pass SLAPOS_TEST_LOG_DIRECTORY and SLAPOS_TEST_SHARED_PART_LIST, as discussed on nxdtest!2

This change to unconditionally create products, to make it more clear
that it's OK for test methods to change the products configuration because
they are reset at the beginning of each tests (they have always been removed
during tear down)

This is used and should not be disabled.

There was an error when clicking this dialog, fix that error instead.

In ERP5JS when redirecting we can use `portal_status_level` to control the appearance of the notification.

This updates the cases when user action could not be performed to redirect with an error level, so that notification appears in orange, not in green (in ERP5JS - in erp5_xhtml_style this has no effect).

accounting, base, trade were updated

so that installed objects are owned by System Processes and we can have faster ownership checking for proxy role scripts.

Portal is the Skinnable object, skin magic belongs there.

Also, modernise it a bit.

testnode use to publish the URL of logs so that Nexedi ERP5 can
display link to "view logs". This URL was an IPv6 URL on a certificate
which does not validate.

Now testnode software release request a shared frontend for these
logs and generate a config file with log_frontend_url set.

testnode now advertise the URL of log using the log frontend url
from config.

Also simplify frontend_url key to manage it using the same way.

SLAPOS_TEST_LOG_DIRECTORY and SLAPOS_TEST_SHARED_PART_LIST have been
introduced recently, they are passed to runTestSuite using the usual
way of running runTestSuite once with --help to inspect supported
arguments and passing the argument only if runTestSuite supports them,
but these arguments are not necessarily heavy to compute and are always
known (unlike for example firefox path which is only known if seleniumrunner
extra software was installed), so simplify all this by passing the
parameters are environment variables.
