We are already closing Storage on shutdown (see nearby Storage.close call in
the patch), but the DB handle was not closed. With classic ZODB it does not
really matter in practice, because not closing DB is only leaking RAM resources
and the program is anyway terminated soon.

However with wendelin.core 2 things are different: in addition to ZODB storage
server, there is also synthetic WCFS filesystem from which files are opened
and memory-mmaped. In runUnitTest we start both ZODB and WCFS servers and we
also shut down them both in the end. The filesystem server can be cleanly
unmounted and shutdown only when there are no opened files left on it.

Wendelin.core 2 client works by complementing each ZODB connection (zconn) with
WCFS-level connection (wconn) to WCFS server. Those two zconn and wconn are
kept in sync by wendelin.core 2 client logic: whenever zconn adjusts its view
of the database, so does wconn. And whenever zconn is garbage collected, so
does wconn is closed to release resources and close corresponding files opened
on WCFS. In addition to garbage-collection, wconn is also closed when zconn.db
- the ZODB DB handle via which zconn was created - is closed. This is needed to
be able to reliably trigger freeing WCFS resources, because even after DB is
closed, zconn can still stay alive forever being referenced from some python
object - e.g. a frame or traceback or something else.

The latter scenario actually happens during runUnitTest run. As the result it
leads to inability to unmount and stop WCFS server cleanly:

    $ ./runUnitTest --load --save --with_wendelin_core -v erp5_core_test:testWendelinCore
    ...
    test (erp5.component.test.erp5_version.testWendelinCore.TestWendelinCoreBasic) ... ok

I've debugged things a bit and even with
kirr/ZODB@bbd03b3a ZODB connection stays alive
being referenced from some frame objects.

-> Fix this problem by explicitly closing ZODB DB nearby tests shutdown before call to wcfs_server.stop

This is not really for errors during the test itself, but for errors when
ERP5TypeFunctionalTestCase manipulates browser to execute selenium test.

This depends on the support in slapos nexedi/slapos!999

It can happen that a test running selenium fail in python, but not in selenium,
like for example test_result_module/20210615-CDADEC14/183
To prevent such tests from being reported as PASS, we make the total number of
failures being the sum of the python unittest failures and the selenium failures.

It happens, for example with erp5_officejs_ui_test:testFunctionalOfficeJSPyodideNotebook
on test_result_module/20210615-CDADEC14/183 that the test is considered as
not running, because the test result table was not populated in time.

Add an explicit wait to prevent such problems.

This fixes commit ea4cb55b.

Our 'rmtree' helper has never been supposed to be called on a
non-existing folder: the ENOENT handling is an unrelated
implementation detail for Python 2.

Also drop erp5.util's rmtree and use the one from slapos.core,
which is a [testnode] dependency.

This is follow-up to 5796a17a (core_test: Add test to make sure that
wendelin.core basically works; nexedi/erp5!1429).

In that commit it was said that testWendelinCore

    "currently passes with wendelin.core 1, which is the default.
     It also passes as live test with wendelin.core 2.
     However with wendelin.core 2 it currently fails when run on testnodes
     ...
     because we need to amend ERP5 test driver

     1. to run tests on a real storage instead of in-RAM Mapping Storage(*), and
     2. to spawn WCFS server for each such storage."

This patch addresses that latter problem to run testWendelinCore under
testnode infrastructure.

@rafael and @jerome suggested that we can force a test to be run on a
real storage via `runUnitTest --load --save` or via `--activity_node=n`.

@rafael also suggested not to generally change the testing driver, but instead
make step-by-step progress and first tag each test that uses wendelin.core with an
option. Let's go this way now: runUnitTest/custom_zodb are taught to launch
WCFS server if wendelin.core usage is requested and software is built with
wendelin.core 2.

With both changes combined testWendelinCore should now pass OK when run
on a testnode with both wendelin.core 1 and wendelin.core 2.

This patch is based on a draft patch by @rafael: https://lab.nexedi.com/rafael/erp5/commit/14e3a777.

This patch also relies on recent wendelin.core 2 wcfs.py rework which
exposed functionality to start WCFS server and to further control it:
kirr/wendelin.core@5bfa8cf8.

Eventhough _getBudgetDict was cached, getAvailableBudgetDict also
calculates getCurrentBudget for each cell, which is also heavy.

With software release test suites, there are probably
files/folders with permission issues.

This firefox setting cause console.log messages or javascript errors to be
printed on stdout, which should help diagnosing failures sometimes.
