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 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

Change all `check_port_listening` promises to `check_socket_listening`
and rename all associated `config-hostname` arguments to `config-host`

instead of downloading a pre-binary that might not match the architecture

Changes configuration files to run repman tests in python3.

done with:

     npm install
     git ls-files | grep -v '\/unstable\/' | xargs ./node_modules/.bin/eclint fix
     git ls-files | grep buildout.hash.cfg | xargs ./update-hash

TODO: There are still direct references to specific version of Python in:
  - slapos component
  - bazel templates
  - nextcloud & theia SR

Filename is split as an URL path, and joined in OS-dependent manner.
Remove corresponding comment in all buildout.hash.cfg files.

Some files and sockets where created in their default location, which
was in the software.
As a result, this software was working only on webrunner or testnodes,
which uses same unix user for software and instance.

Instead of letting `python setup.py test` install the depencies, use
buildout way of installing the eggs.

This software use `interpreter` recipe of `zc.recipe.egg` to install a
python with all eggs pre-installed. This is a way to get all the
dependencies at install time instead of getting them at run time from
pypi when running `python setup.py test`.
`erp5.util.testsuite` has been extended to support a parameter to
specify which python interpreter to use.

One issue is that this way of installing eggs by buildout cause chicken
and egg problem: cloning repository containing `slapos.recipe.cmmi`
needs git, and to compiling git needs `slapos.recipe.cmmi`.
The consequence of this is that re-running software will install too
many parts again.
One solution for this would be to clone `slapos.recipe.cmmi` with a
`git` command provided by testnode or system package.
Another solution would be to not install `slapos.recipe.cmmi` develop
egg, simply install the egg from it's current pypi version while
installing the software (running tests will be from the git checkout
anyway).
For now this is open issue.

Another point of attention is that `python setup.py test` install the
requirements listed in `test_requires`, but `zc.recipe.egg` does not
provide a way of installing these. Some of our packages have `[test]`
entrypoints, in this case, the software installs the test entrypoints.
For others, we install the eggs.

Other improvements:
 * use a simple `slapos.recipe:wrapper` instead of `slapos.cookbook:egg_test`
 * fix the typo in repository name erp5-util-repository ->
   erp5.util-repository ( this mean we will have to fix the test suites in
   nexedi ERP5 )
 * document "what is this software" and a scenario of how this software
   can be used to develop slapos eggs.
 * switch to buildout-hash.cfg for easier template hash management.

monitor: move scripts wrapper and logrotate conf to buildout, uses some new promises from slapos.toolbox

monitor was updated in slapos.toolbox to not generate promise launcher scripts anymore. All
generated scripts are now in buildout.
Monitor promise run script is removed from cron, slapgrid is used to run promises.
Replace some old promises by the new ones from slapos.toolbox. Cleanup monitor configuration.
Monitor report and monitor-promises directory are now obsolete.

stack/monitor: Create srv/monitor/private/monitor-log directory. It is specified by slapos.monitor.monitor.Monitoring.

stack/monitor: Add a random delay of maximum 60 seconds to all monitor cron jobs to avoid high load at the first second of every minute.

This reverts commit ee8e3fb2.
