Description of problem:
Client deployments are failing during containerized deployment via ansible for 3.x

Version-Release number of selected component:
Red Hat Ceph 3.0 for Red Hat Enterprise Linux 7

How reproducible:
Can be reproducible with automation script or manual deployment using ansible docker playbook on RHEL following this manual: https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/3/html/container_guide/deploying-red-hat-ceph-storage-in-containers

Steps to Reproduce:
1.create environment to statisfy hosts file (RHEL)
2.install ceph-ansible to installer node
3.update ansible configuration with provided hosts file and all.yaml content
4.run docker playbook

or

try https://ceph-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/view/RHCS%203.x/job/wip-vshevche-ceph-containerized-ansible-sanity-3.x/ Jenkins job

Expected results:

Client nodes are deployed and configured without fails. No fails in play recap.

Additional info:
Cleint deployment behavior is not clearly specified in the containerized deployment manual and considered the same as for non-containerized deployment 3.x
