Without this we get too fresh virtualenv while we have packages versions
conflicting with it in constraints.txt. Also disable downloading random
(fresh) versions of packages by virtualenv and remove --upgrade from
pip. setuptools package is not mentioned in constraints.txt because it
is expected to be installed at proper version by virtualenv, so we
shouldn't upgrade it to later versions.
Right now we end up installing latest virtualenv 15.1.0 with
setuptools 34.0.0 which depends on packaging>=16.8 while for Newton we
have packaging===16.7.0 in constraints.txt

All Python modules inside fuel-ccp are installed via `pip install` from
official PyPi repository. That might sometimes be not convenient, in
case somebody wants to use own repository.

Constraints file is taken from requirements repo URL, pip in venv is
configured to always use it and never use cache dir (it's a very common
option in our Dockerfiles).
Note that the plan was to get URL from config but there's currently no
good place in configs for it.
Also removed --system-site-packages option to virtualenv as it defeats
the purpose of constraints.

Originally we used libmariadbclient-dev headers, which does not really make
sense. Mygrating to stock libmysqlclient-dev makes live easier and removes the
dependency on custom MariaDB repositories.
