Description of problem:
=======================
ceph-ansible should install package as per node role but it's installing MON packages on OSD node and OSD packages on MON node.



Version-Release number of selected component (if applicable):
=============================================================
ceph - 10.1.0-1.el7cp.x86_64
ceph-ansible-1.0.3-1.el7.noarch


How reproducible
================
always


Steps to Reproduce:
===================
1.create cluster having multiple mon and osd node and make sure osd nodes and mon nodes are different.
[mons]
magna042
magna051
magna063

[osds]
magna066
magna067
magna074

[rgws]
magna084

2. run 'rpm -qa | grep ceph' on each node


Actual results:
===============
MON node:-

[root@magna063 yum.repos.d]# rpm -qa | grep ceph
ceph-mds-10.1.0-1.el7cp.x86_64
