Fixes merge request !1011

ZEO 5.2.3 fixes several client concurrency bugs that could result in
data corruption. See changelog in https://pypi.org/project/ZEO/5.2.3/
for details.

trollius 2.2.post1 -> 2.2.1 update fixes "bad file descriptor" problem for ZEO5.
See https://github.com/zopefoundation/ZEO/issues/176 for details.

futures 3.2.0 -> 3.3.0 update brings in more efficient use of threads in
ThreadPoolExecutor. See https://github.com/agronholm/pythonfutures/blob/master/CHANGES.rst#330
for details.

Test was sometimes failing with:

======================================================================
FAIL: test_http_get (test.TestRepman)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "slapos-repository/software/repman/test/test.py", line 81, in test_http_get
    self.assertTrue(cluster['isProvision'])
AssertionError: False is not true

It can take a little time before everything is ready and we don't have a
promise for this, because it's really application level.

See merge request nexedi/slapos!1031

This propery has a default, which indicates that it is not required.

https://rjsf-team.github.io/react-jsonschema-form/ can handle this
correctly, but needs a default along with the const.

Most tools work without this, but it's cleaner to define this anyway

This reverts commit f34aeeab.

this had the side effect of installing `promise-check-free-disk-space` which
is still used - at least by caddy tests.

In the test output, there are lots of tracebacks like this one:

    "./software/caddy-frontend/test/test.py", line 534, in do_GET
        for header in config.pop('X-Drop-Header', '').split():
    AttributeError: 'NoneType' object has no attribute 'split'

this does not seem to impact the test result, but it makes the result hard to
read.

Now that slapos-node-software service does not use --all we have to use another
approach for this test which re-installs an already installed software.

Use the slapos-node-software-all services which was made for similar use cases.

This was changed as part of b049c057 (upgrade to slapos.toolbox version
0.123, 2021-07-19), but this is not a slapos.toolbox promise plugin, it's
still an old style promise.

when running on test nodes some promise fail because testnode itself has
monitoring and the promise connects to testnode's own monitoring.

This reveals a real problem, but we need to fix testnode first to be able
to use this.

With gcc 6.3.0 we see build failures:

    error: no matching function for call to 'tesseract::STRING::STRING()'

According to https://github.com/tesseract-ocr/tesseract/issues/3210#issuecomment-774599019
minimal gcc version is version 7.

This probably started to break since d6dd75df (component/ghostscript:
version up 9.54.0, 2021-05-25) and 5f616dd7 (component/tesseract: version
up 4.1.1, 2021-05-20).

This gcc is needed for both tesseract and ghostscript, because ghostscript
build again its embedded copy of tesseract.

In b049c057 (upgrade to slapos.toolbox version 0.123, 2021-07-19), we
translated check-secure = 1 to config-http-code = 401, but check-secure = 1
also accepted responses with status code 200.

Thoses promises where checking servers without authentication enabled, they
reply with 200, so update the promises accordingly to expect 200.

This fixes a username/password confusion from c536eb7c (stack/monitor:
change frontend url promise to use username/password, 2021-07-26)

This change has no effect on stand-alone setups (which is what is
automatically deployed).
On setups configured to replicate from another database, it allows them to
takeover the role of the primary server, which allows rebuilding a
redundant setup. On such setup, the cost of this option is the extra I/O
load of binlogs being written to (in addition to the relay log and
database), and the corresponding disk space use.

Commit 7d1ea024 (version up: zc.buildout 2.7.1+slapos013) switched buildout to
not use egg wheels, even for wheels that are source-only without any binaries.
As the result some eggs stopped to install because they setup_require other
eggs and neither buildout handles setup_requires automatically, nor there is
explicit setup_require declaration in corresponding components.

An example of such egg is python-dateutil: it setup_requires setuptools-scm,
and without switching python-dateutil to zc.recipe.egg:custom with
setup_requires the build fails.

The way 7d1ea024 used to workaround this is to mark all such eggs with :whl
suffix marking them that "it is ok to use wheel for this particular egg". The
complete list of eggs for which such markings was done in 7d1ea024 is:

    ipykernel
    plantuml
    mock
    PasteScript
    backports.functools-lru-cache
    cliff
    stevedore
    CacheControl
    pytest-runner
    jsonschema
    lockfile
    python-dateutil

However this list is not really complete because after 7d1ea024 the build
started to fail for e.g. zodbtools test:

        Traceback (most recent call last):
          File "<string>", line 10, in <module>

and similarly for pygolang and nxdtest tests.

I would be more comfortable if the fix would be to teach buildout to either
handle setup_requires automatically, or to automatically install wheels if the
wheel is source-only. However, given the way - that 7d1ea024 started to use
to handle such situations - let's fix this via explicitly marking pytest, and
other related eggs that setup_require something and are source-only, as :whl.

NOTE we did not notice the problem earlier because on testnodes, after the
switch to new buildout, pytest egg was already installed and incremental
rebuild did not need to reinstall pytest egg. So most of pygolang and zodbtools
test results remained in "ok" state, and only zodbtools-kirr, that was recently
reconfigured or changed testnode, indicated this issue. That's why the problem
remained unnoticed for a long time.

This introduces some breaking changes to the check_url_available
promise:

- http_code has been renamed to http-code
- check-secure = 1 has been deprecated; http-code = 401 should be used
  instead

See merge request nexedi/slapos!1011

also apply the change in software/theia/test/dummy/software.cfg for consistency

  This is a partial port, just to have more tests that
  weren't afected by the patches for keep apache as entry-point
  of the backend.
