Use runTestSuite interface to launch tests that request instances
on actual SlapOS cloud.

As described in https://github.com/msgpack/msgpack-python#major-breaking-changes-in-msgpack-10
raw is False by default for unpacker so we receive strings, not bytes

See merge request nexedi/slapos!1490

ZODB4 does not support python3

These must be installed through dependencies, but we explicitly need
scripts from supervisor because this is used by slapos-core tests

on python3 we use lzma directly

This software only use nodejs for a simple build step, it should be OK
to use any version.

Hello up there.

I've noticed that wendelin.core tests became failing to build and
automatically disabled some time ago. Not good. I've tried to fix build
failures. Please see individual patches for details.

After probably 02fad6a8 (component/{numpy,scipy}: Version up for Python3.)
pygolang test build started to fail in numpy compilation as shown in the
appendix. The failure is correct as pygolang never explicitly depended on
${numpy:egg}. We did not noticed before probably because in earlier versions
numpy did not required Cython to be present at install time.

-> Fix it by explicitly adding ${numpy:egg} to pygolang[all_test] dependencies.

Apendix. Log of test build failure
