Add -s --ssl option to xm migrate

This patch adds -s --ssl option to xm migrate. It will override
xend-relocation-ssl setting in /etc/xen/xend-config.sxp.

When mix deploy xen 3.2 and xen 3.3 servers, it's convenient to have a
command line option rather than modify /etc/xen/xend-config.sxp every
time.
