This is to reproduce crashes with mariadb 10.3

I believe that in the live system where we observe the crash we have expand
taking more than 5 seconds, and that if we use a shorter timeout here the crash
happens more often.

The original intention is to reproduce a crash with mariadb 10.4

At this point nothing is properly integrated and that's definitely not where we
should be calling ERP5Site_createUpdateSimulationScalabilityTestData

all member of random module are available (because in ZopeGuards, there's a
random.__allow_access_to_unprotected_subobjects__ = 1), SystemRandom class
also is, but Random class was not, even though there should be nothing unsafe
in this.

This is needed if we want to use a random number generator with a fixed seed
to get reproductible results. We could use random.seed module level function
but since this is also used by several things in ERP5 this does not produce
reproductible sequences.

Before we had the sub-documents exported as properties of container document
for some reason. Now they are exported as separate documents, as expected.

runTestSuite accept a --test_node_title argument, which is used in
createTestResult API call, so that task distributor can keep track of which
node executed which task, but since it was not passed, we did not know which
test node executed which test result line.

Remove some unused code and enable coding style

See merge request nexedi/erp5!1263

Change the conditions from getAggregate to hasAggregate and add a portal_type filter
of getPortalDocumentTypeList, since in reality these check for Attachments that are Document Types
stored in ERP5, so types like 'Internet Message Post' should not be considered.

Plus, xml changes, since there was no commit in these fields in the last 9 years

ZODB Components: Migration dialog: list_selection_name must be explicitly named for mapply() to pass it from REQUEST.

Payments made on the date of previous bank statement but not at 00:00 were
not taken into account in this constraint, which leaded to false positive preventing
to open the next bank reconciliation when previous one had a payment with an
accounting date on the day of the bank statement but not at 00:00

Instead of only checking that an error is reported, check the expected
error message, so that we are sure that this test really covers what
it's supposed to cover.

Now that testnode client is supposed to pass test node title,
make sure that on the server side we can display this information.

runTestSuite accept a --test_node_title argument, which is used in
createTestResult API call, so that task distributor can keep track of which
node executed which task, but since it was not passed, we did not know which
test node executed which test result line.

This was never finished and would probably not be implemented this way,
so let's remove.

ERP5 functional tests are failing too often, until we improve the tests or the
code so that we don't have these intermitent failures, restart the failed tests
a bit automatically.

This is of course not good, because it's hiding problems, but the current state
of the test suite with many randomly failing test makes that we sometimes miss
when permanent failures are introduced.

these actions are not ready to be used by end users

Persons created before the introduction of ERP5 Login and user_id will only
have a user_id after migration if they were already user before migration,
otherwise they will not have a user_id and creating assignments and ERP5 Login
for this person creates a user which can not log in the system.

To make it possible for these persons to login anyway, we ensure person has a
user id when validating a login

This is bc67c2c4 again, but with a proxy role
on the interaction workflow and a non regression test to cover the problem with
the first version of that commit.

repair tests after nexedi/erp5!1207

Most parts of this patch come from wendelin, plus the tests and some fix.

erp5_jexcel_editor is now installed by this profile, since it's a
dependency of erp5_officejs_jquery_app

coding style test is failing, this business template cannot use
WebSection as a prefix for skin unless Web Section portal type exists.
Depend on erp5_web so that erp5_web gets installed in tests.

User must be informed that such query is not handled.
