slapos-testing: use buildout to install eggs

Instead of having running test installing eggs with setuptools during `python setup.py test`, which fails for `caucase` because one of its dependency (namely `cryptography`) cannot be installed so easily, we want to install the dependencies via buildout, using the same installation methods than in the actual software profiles using our eggs.

What I initially believed would be a small change turned out to be a long journey, especially because of using a develop version of `slapos.recipe.cmmi` caused signature changes in the parts installed by this recipe ( `git`, `openssl` etc - some parts that takes a bit of time to install ) so I had to fight with the software being reinstalled each time. Even though the cases which leads to reinstallation are understood (this even involved fixing a bug in buildout slapos.buildout!14 ), this is still the case. Some solutions are proposed in the commit message of f4b6eeda , but this reached a state where we can consider first merging with this known problem or discuss ways of improving that before merging if it's considered as blocking. Current state is that it takes one hour to re-install what has to be reinstalled and run the test suite on test runner.

Despite this issue, this approach already improve things, because:
 * `caucase` tests are running (and passing)
 * some `slapos.cookbook` are improved so that they reuse eggs from the buildout and do not install again eggs when the are run.
 *  ... and some other small cleanups

This depends on erp5!619 on the `erp5.util` side.

+# Slapos egg tests
+
+This software release is used to run unit test of slapos eggs.
+
+The approach is to use setuptools' integrated test runner, `python setup.py test`, to run tests.
+
+The `python` used in this command will be a `zc.recipe.egg` interpreter with
+all eggs pre-installed by this software release.
+
+Nexedi staff can see the results of this test from the test suite
+`SLAPOS-EGG-TEST` in test result module.
+
+
+Here's an example session of how a developer could use this software release in
+slaprunner to develop a slapos egg, in the example `slapos.core`, to make
+changes to the code, run tests and publish changes.
+
+```bash
+# install this software release
+SR=https://lab.nexedi.com/nexedi/slapos/raw/master/software/slapos-testing/software.cfg 
+COMP=slaprunner
+INSTANCE_NAME=$COMP
+
+slapos supply $SR $COMP
+slapos node software
+slapos request --node=node=$COMP $INSTANCE_NAME $SR
+slapos node instance
+
+# The source code is a git clone working copy on the instance
+cd ~/srv/runner/instance/slappart0/parts/slapos.core/
+
+# make some changes to the code
+vim slapos/tests/client.py
+
+# run tests, using bundled python intepreter with pre-installed eggs dependencies
+~/srv/runner/instance/slappart0/software_release/bin/python_for_test setup.py build
+
+# when satified, commit changes
+git add -p && git commit
+
+# add developer's fork remote (this is only needed the first time)
+git remote add my_remote https://lab.nexedi.com/your_username/slapos.core.git/
+
+# push the changes
+git push my_remote HEAD:feature_branch_name
+
+# then submit merge request
+```
