Description of problem:
The ceph-mon package contains ceph-rest-api. We do not support this API downstream in 3.0. With ceph-mgr built in now, we should delete ceph-rest-api entirely.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. yum install ceph-mon
2. rpm -ql ceph-mon | grep rest
ceph-rest-api files are present (for example, /usr/bin/ceph-rest-api)
no ceph-rest-api files are present.
This is removed in upstream nautilus.
