From: Peter Xu <peterx@redhat.com>

Migration documentation is growing into a single file too large.  Create a
sub-directory for it for a split.

We also already have separate vfio/virtio documentations, move it all over
into the directory.

Note that the virtio one is still not yet converted to rST.  That is a job
for later.
