    Use default disk image size for centos/7

    Latest centos/7 image from atlas now comes with 40 GB disk size which
    is equal to the virtual_size we specify in the Vagrantfile. Libvirt
    provider doesn't like it and produces an ugly stacktrace.

    The new default value now sufficient run kolla properly and we can
    remove the code that artificially increased the disk size.
