Work around pip resolver issues on Python 2.7
Work around pip resolver issues on Python 2.7

On Python 2.7, the latest pip version is failing to install a good
set of packages, because it tries to install alembic > 1.6, which
requires SQLAlchemy >= 1.3.0, which is not compatible with ara < 1.0.0.

As a quick workaround, let's pin those two libraries to ensure we
get a clean virtualenv.
