    Reduce postgres and backup filesystem sizes

    Since openstack is a separate application we reduce the preallocated
    size for the postgresql database and for the backup filesystems.
    Currently postgres fs allocation is 40G for disk size greater than
    240G and 20G for disk size between 240G - 186G inclusive.

    This commit cuts these defaults in half:
     o postgresql will be 20G for large disk size and 10G for small disk
       size by default.
     o backup filesystem will be adjusted to 25G and 20G respectively to
       reflect the reduction of postgres fs allocation.
