Change Ironic bm flavor to use ephemeral partition

Adds use of the IRONIC_VM_EPHEMERAL_DISK variable to devstack
that will alter the flavor to specify an ephemeral partition
size. This change creates a 1 GB ephemeral partition, which
will be deducted from the overall disk size (IRONIC_VM_SPECS_DISK).
