Make python print statements python3 compatible

The restart_osd_daemon.sh generated from the j2 template
contains a python call which uses 'print x' instead of
'print(x)'. Add the missing parentheses to make this call
compatible with both 2 and 3.

Also add parentheses to other python print calls found
in roles/ceph-client/defaults/main.yml and
infrastructure-playbooks/cluster-os-migration.yml.
