Restrict nova migration ssh tunnel
This change enhances the security of the migration ssh tunnel: - The ssh authorized_keys file is only writeable by root. - Creates a new user for migration instead of using root/nova. - Disables SSH forwarding for this user. - Optionally restricts the networks that this user can connect from. - Uses an ssh wrapper command to whitelist the commands that this user can run over ssh. Requires the openstack-nova-migration package from https://review.rdoproject.org/r/6327 bp tripleo-cold-migration Change-Id: Idb56acd1e1ecb5a5fd4d942969be428cc9cbe293 (cherry picked from commit f8ca94a5b7c7658631f5b0a9b010251ebbcff65e)
