ceph-mon: adds static: no to an include to avoid an ansible bug

Adding that avoids this bug:

https://github.com/ansible/ansible/issues/18206

Without that you'll get failures like:

TASK [ceph-mon : set keys permissions]
*****************************************
task path:
/home/andrewschoen/ceph-ansible/roles/ceph-mon/tasks/ceph_keys.yml:31
fatal: [mon0]: FAILED! => {"failed": true, "msg": "'dict object' has no attribute 'stdout_lines'"}
