James Slagle 94f580370d Add an environment to use a swap partition
This environment can be used with AllNodesExtraConfig to enable swap on
a device with the given label as specified by the swap_partition_label
parameter.

If Ironic is used to create the swap partition, the partition will have
a label of swap1, so that's a reasonable default for the parameter.

The partition is also written to /etc/fstab as a swap mount so that it
will be enabled on reboot.
