python/samba: add alias for ConfigParser for PY2/PY3 compatability
ConfigParser module changed name to configParser in PY3, additionally
the behaviour regarding interpolation has changed. ConfigParser now
has a default interpolation param whose behaviour demands that '%' is
escaped. To maintain behaviour with the python2 version this default
param needs to be changed. Add some alias(s) and 'shim' Configparser
symbol in samba.compat to cater for this.
