    Handle None value properties in glance-replicator

    bug 1208417

    In glance-replicator, all image properties in the master glance are
    synced to the slave. But there are circumstances(kernel_id or
    ramdisk_id, etc.) when image properties in the master are None.
    glance-relicator doesn't handle this issue, thus all such properties
    are trasnlated to the string 'None' in the slave glance, which is
    incorrect.

    This patch fixes this problem by add a check before post metadata to
    the slave glance. All None properties are translated to '' before
    posted to slave glance.
