This patch introduces a new environment variable in order to allow running
tests with different database backend. This is useful particularly for running
tests inside container. With this change, it is possible run tests in following
combinations:
* Python 2 and SQLite
* Python 3 and SQLite
* Python 2 and PostgreSQL
* Python 3 and PostgreSQL
Package python-psycopg2 is installed in both Dockerfile-tests and
Dockerfile-tests-py3 in case of running tests with PostgreSQL.
A new script contrib/run-unittests.sh is added to make it easy to run tests. An
example:
contrib/run-unittests.sh --py3 --with-pgsql
that runs tests with Python 3 and PostgreSQL.

This also moves the methods load_mmd and load_mmd_file to
module_build_service.utils.general.
This also removes some MSE unit tests with a mix of positive and
negative streams since this is not supported in libmodulemd v2. The
user will be presented with a syntax error if they try to submit
such a modulemd file.
