With the default umask of running slapos node, the default umask create files
that are only readable by user, not by group:

    slapuser10@COMP-1234:~$ ls -al /opt/slapgrid/bf0ccebdbd76d491bcbe16b7998529b2/parts/tesseract/share/tessdata/
    total 125296
    drwxr-x--- 4 slapsoft slapsoft 4096 Jul 13 05:57 .
    drwxr-x--- 3 slapsoft slapsoft 4096 Jul 13 05:57 ..
    -rw------- 1 slapsoft slapsoft 44366093 Jul 13 05:57 chi_sim.traineddata
    drwxr-x--- 2 slapsoft slapsoft 4096 Jul 13 05:57 configs

    drwxr-x--- 2 slapsoft slapsoft 4096 Jul 13 05:57 tessconfigs

but when using multiple users, partitions users are members of slapsoft group,
so these files needs to be group readable.

listening-ip parameter is now mandatory

Now that slapos node instance no longer use --all ( nexedi/slapos.core!278 ),
some software release test revealed some problems with softwares,
either missing promises or maybe something that needs to be handled in slapos.core.

Using --all was wrong and we want to stop doing this now. Instead of fixing these software now, we keep the old behavior
of using --all only for the softwares with missing promises.


See merge request nexedi/slapos!969

This avoids having multiple monitors trying to listen on the same port
when using replicate instances.

Thanks to minimising amount of changing parameters of the wrapper, by setting
RAM and CPU to "init" values, it's possible to not restart the wrapper in case
of device hotplugging in for changes of those parameters.

Note that this shows regressiong to enable-device-hotplug which happened
after upgrade to qemu 5.2.0 in 8dc22418.

slapos.toolbox is added in order to use qemuqmpclient.

Tests depend on pycurl, which has to be provided with component, as
otherwise is uninstallable.

Fixes 75af5cd3

This softwares have some missing promises, so we keep using slapos node instance
--all in the test, so that test keep passing after we change standalone slapos
to not use --all anymore.

monitor-globalstate (which is supposed to create monitor configuration file
accessed by HTTP as .../public//monitor.global.json) runs by cron every 2
minutes. This crontab also uses randomsleep to add a delay - but there's a
promise waiting for this monitor configuration file to be available, so the
instanciation had to wait for this and if this was sometimes causing problems
in software release tests because promise did not succeed fast enough.

To prevent this pattern where slapos node instance has to wait for a crontab
to be executed, we run that script a first time from buildout.

Also improve the recipe `switch-softwaretype' by catching the possible errors.

This is based on commit "Firefox Version Up to 78.1.0esr", but it does not
replace the default firefox, just enable a new version for now.

This is a "minimal" version up to fix https://bugs.gentoo.org/580392 which
appears now that we build with gbm

some components, like binary chromium needs libgbm, which is part of mesa, but
build only when enabled.

* [slapos-master](https://nexedijs.erp5.net/#/test_result_module/20210629-DE509CB3/23) is failing in checkSoftware step, because:
  * wcfs is linked against system zlib (fixed in this MR)
  * the .so in the build directory have missing references. I think we don't need to check in build folders and also liblibgolang is missing, but it's not a problem because of the way we load dynamically at runtime, so I suggest changing checkSoftware in nexedi/slapos.core!317
* [gitlab](https://nexedijs.erp5.net/#/test_result_module/20210629-DE509CB3/10) is failing for some time because mimemagic have been yanked from rubygems. This is a minimal change to get the test running again, to prevent other problems to sneak in while we don't have tests

On wendlin.core 2, wcfs uses github.com/DataDog/czlib which uses zlib. We also
need to instruct linker to set a rpath for slapos' zlib, otherwise the system
one will be used.
