Bug#889653: netdata: missing python module 'pyyaml2'

[Guillaume Clercin]

With user netdata, if I want to test a python module, I run:
netdata@kazoo:/usr/lib/x86_64-linux-gnu/netdata$ ./plugins.d/python.d.plugin 1 
debug trace mdstat
Traceback (most recent call last):
  File "./plugins.d/python.d.plugin", line 31, in <module>
    from bases.loaders import ModuleAndConfigLoader
  File 
"/usr/lib/x86_64-linux-gnu/netdata/python.d/python_modules/bases/loaders.py", 
line 15, in <module>
    from pyyaml2 import SafeLoader as YamlSafeLoader
ImportError: No module named pyyaml2

According the file 
"/usr/lib/x86_64-linux-gnu/netdata/python.d/python_modules/bases/loaders.py",
python2 module require pyyaml2 and python3 module require pyyaml3.

Import thing, I modified 
"/usr/lib/x86_64-linux-gnu/netdata/plugins.d/python.d.plugin"
in order to fix the path of "PLUGIN_CONFIG_DIR".
