The use of an entry point was considered in order to provide
an `odoo` command in the path for the packages users, but the
generated entry point will first check that all the things in
install_requires were provided in a not bright way: it'll check
that it matches a distribution name. This does not work because
python-chart does not have the distrubtion name "pychart" which
is provided by the python-pychart package in debian jessie. Same
for suds-jurko which is provided by python-suds in debian stretch
but does not have the distribution name "suds".
Also, adapted the packages tests to these cli changes.
and move it under the setup package. Since the rename of the
openerp directory into odoo, having a script named "odoo.py"
conflicts with a package named "odoo".
