The example from `software/slapos-sr-testing/README.md` in slapos repository uses a path with `~` for shared parts, but this was not supported.

Also, what was not supported is to use `setUpModule` more than once, but erp5 SR tests are starting to do this.

See merge request !196

In slapos:manager_list it is possible to enable list of managers, but as they
have to be configurable support sections for each manager by [manager:x]

So having configuration file like:

[slapos]
manager_list = mgr

[manager:mgr]
key = value

Will allow for the mgr manager to read values from manager:mgr

Slapos is started the first time the StandaloneSlapOS is instanciated,
then, in each class teardown we stop slapos, so the second time
setUpModule is executed, the slapos is not started yet.

Start it one more time in setUpModule to ensure it's started in this
scenario.

In cloudooo software release we are installing libreoffice and wkhtmltopdf as binary.
These parts contain executables that seem to have missing dependencies, but there are wrapper setting library path, so they can be ignored.

See merge request !195

python interpreter is sometimes referenced only in bin/buildout's
shebang, even if not used anymore in any software, if it was used to
initially created the buildout. In that case, the part should still be
considered as used and not pruned.

See merge request !194

Some information (like the actual buildout command used to invoke buildout ) is shown only when slapos node runs with `-v`

When running with shared parts from slaprunner, we'll have path with
double slashes like:

    /srv/slapgrid/slappart3/srv//runner//shared/libexpat/468993ea3777c1a342102bc1c4b43425/lib/libexpat.so.1

because slaprunner has some paths with double slash.

See merge request !191

In this way is possible to follow up deployments more closely.

  This should be ensured by configurator

The form just request inform the user to select another name

On certain cases, the invoice is created later on by activies.

This script was introduced for anonymous payments but the procedure was replaced.

When running with shared parts from slaprunner, we'll have path with
double slashes like:

    /srv/slapgrid/slappart3/srv//runner//shared/libexpat/468993ea3777c1a342102bc1c4b43425/lib/libexpat.so.1

because slaprunner has some paths with double slash.

  Add tests for SubscriptionRequest_verifyPaymentTransaction

This command was identical from slapos cache lookup, but the meaning is
different.

Also update to use download-cache-url from config.

This is what most of tools understand, test_requires is something that
only python setup.py test uses.

In our normal operations, we are not using PYTHONPATH but using buildout
to generate wrappers. We are still using python setup.py test to run
tests, which sets PYTHONPATH to the eggs used by this python and this
cause issues when this python starts subprocesses, especially when it
starts another version of python which is supposed to use a different
set of eggs.

also add missing test for slapos node boot
