[RFC v2 02/15] test: Add utility library for python scripts

[Mikel Astiz <mikel.astiz.oss@gmail.com>]

From: Mikel Astiz <mikel.astiz@bmw-carit.de>

Several convenience functions/features will be removed from BlueZ's
D-Bus API, and therefore a utility library is required to avoid
boilerplate code in the test scripts.
