rolling_update: fix pre and post osd upgrade play

when using --limit osds, the play before and after osd upgrade are
skipped because we use `hosts: "{{ mon_group_name | default('mons') }}[0]"`
using `hosts: "{{ osds_group_name | default('osds') }}" with
`delegate_to` to the first monitor addresses this issue.
