Add top-level setup.py

This file is basically a symlink to "python/setup.py" expressed in
python code.  If python executes "setup.py", it will be effectively
executing "python/setup.py".
This is required to allow PIP installation from a git repo, which assumes
that "setup.py" is at the root.

e.g.:

pip install 'git+http://github.mtv.cloudera.com/Starship/cm_api#egg=cm_api-13.0.0'
