KeyError on non-ceph ansible group

[haklein]

When having other groups in ansible.cfg which do not match the usual Ceph pattern (mons, osds, rgws), a KeyError is thrown:

# ./ceph-medic check
Host: rdh-hw20              connection: [connected  ]
Host: rdh-hw20              collecting: [paths]Traceback (most recent call last):

Ansible cfg snippet:

[test]
rdh-hw20
rdh-hw21

[mons]
rdh-cu-8
rdh-hw16
rdh-hw19

[osds]
rdh-cu-8
rdh-hw16
