This runTestSuite uses "python setup.py test" to launch the tests at
a certain folder.

The runTestSuite can upload results using TaskDistribution.

This code is generic enough to be used by others libraries.

The code on ERP5TypeTestSuite is preserved for backward compatibility for
now, until it got updated.

Update now, force the reload of all alarm promises.
