All CMF Products are using eggtestinfo as a setup egg (which is
no longer the case after 2.4.0)

Our schemas test check all files if they are present, but it so far it did not check
that the request and response schema referenced in software.cfg.json were really
existing and they were missing for some softwares.

This extends the test to check that request / response exists and add missing responses for cdn-me and srslte

1.0.167 can not longer be installed, 1.0.167.1 is 1.0.167 with a fix
backported.

pyrsistent has a setup_require of pytest-runner. Buildout installs
setup_require from their latest version, regardless of [versions]. When a
new version of pytest-runner was released without python 2 support this
broke installation of software releases on python 2.
