Security hardened images with partitions fail because not enough disk space for /var partition

[Yolanda Robla]

When using security hardened images, the size of the partitions are fixed. We gave a fixed size of 7G, that worked in previous tests, but some content changes now require /var to have 7.3G at least. So we need to increase the size of the partition, and the global size of the generated image.

    Increase the /var partition from 7G to 10G

    Latest contents in overcloud image caused the need to have at least
    7.3G free for /var partition, while we dimensioned for 7. Increasing
    that to 10G, to fix the issue, and also be prepared for future
    content increases, and give more room for installation.
