This will replace Computer and Computer Partition

   If the mariadb is more recent (and consitent) them the ZODB, it isn't needed to full reindex since all
   changed objects are visible in the catalog. So it is safe enough only partially reindex.

Until now, standalone was running slapos node software/instance with --all flag
which force installing software or processing software, unlike "normal" slapos
node which no longer install on software once they are completed and only process
instances when they are requested with different parameters or when they have
failing promises.

We stop using the --all flag, to behave like a normal slapos node.

This reveal missing promises in some softwares, after this change, waitForInstance
can return faster. This reveal test failures with some softwares where the
instanciation step request other instances, but without having a promise to wait
for their requests to have been sucessfully processed; in this case waitForInstance
return too early.

We keep an "slapos node software --all" API to force reinstalling software, this
can be useful for scenarios like erp5testnode, or software release development.

We also keep an hidden "slapos node instance --all" API, so that we can keep
running tests for software releases with missing promises.

This test suite is for run the tests in the erp5-doc repository.
Put it in this repository is because the testpages in the
erp5-doc/erp5_slapos_tutorial need slapos-master recipe to configure the
erp5 instance.

Old slapgrid version will use the "Hosting Subscription" term during
search.
Add a new Skin Selection to rewrite the search query on the fly.

Add a new web site to not rely on the generic one, as it prevent specific customization

It is needed for now to allow migrating the module

force_install prevents removing content (python script, form fields, ...) when updating a bt5.

liblibgolang from pygolang is used in wendelin and because of a current
limitation of setuptools_dso we don't have rpath on libraries for python
extensions linked with pygolang, but at runtime we import pygolang before and
there's no issue at runtime.

This can be useful for scenarios where shared objects are dynamically loaded at
runtime, after having pre-loaded dynamically some shared objects they depend on.
