[2/2] incubator-ariatosca git commit: ARIA-76 Parallelize PyTest

[em...@apache.org]

ARIA-76 Parallelize PyTest

Use the PyTest xdist plugin to parallelize tests in boxed subprocesses.
Through benchmarking we discovered that paralellizing on the number of
CPU cores ("-n auto") provides the best times.

Also update all our testing dependencies.
