twisted_ipa is a module expected to be used by other python scripts, so
move it to osmopy dir to be installed as a lib (in python path) so it
can be later used.
twisted_ipa has some features to use it standalone for testing purposes.
This feature can still be used from new installation path.

Having the scripts in the same directory with library code means that
it'll be installed unconditionally regardless of version check in
setup.py which makes it impossible to write separate tests for python 2
and 3. Fix this by moving the scripts into separate directory and
adjusting init and setup files accordingly.
This is necessary for implementing proper CI tests in follow-up patches.

Those are generic enough and can be used as advanced example of uzing
CTRL interface from python on top of osmo_ipa.
