Nova ironic driver ignores the "swap" field from flavor

[Lucas Alvares Gomes]

The nova Ironic driver should look at the swap field in the flavor and map it to Ironic, just like it does with the disk size[1]

    If no swap is specified default to 1MB

    After a244d1bc7b the Nova Ironic Driver will add the pxe_swap_mb parameter
    using the value in the flavor (which defaults to 0 if not specified). In
    the Ironic code we had something like get('pxe_swap_mb', 1) to prevent
    the swap size for being 0, but that get() won't work anymore because the
    pxe_swap_mb is set. So this patch is taking another approach to force
    the the pxe_swap_mb parameter to be > 0.
