Port the deploy stage from the development branch

[odarbelaeze]

Let's try to enable the 0.12.4 deploy through travis.

Thanks @odarbelaeze!

Just to check: I seem to remember some issues with the pip version. Is this going to apply here as well or not?

Coverage decreased (-0.06%) to 48.284% when pulling 099200a on odarbelaeze:port-travis-configuration-from-develop into db12cdd on aiidateam:release_v0.12.4.

required_version = StrictVersion(PIP_REQUIRED_VERSION)
    installed_version = StrictVersion(pip.__version__)

    if installed_version < required_version:
        print 'The installation requires pip>={}, whereas currently {} is installed'.format(required_version, installed_version)
        sys.exit(1)

    bin_folder = path.join(aiida_folder, 'bin')

No, there's no problem building aiida with the 19.x version of pip. I just tried in a fresh machine:

$ docker run --rm -it -v $PWD:/code -w /code python:2.7 /bin/bash
root@947c08f49da0:/code# pip --version
pip 19.1 from /usr/local/lib/python2.7/site-packages/pip (python 2.7)
