Bug 1719667

Description of problem:

[1] switched to run nova-manage discovery as non root user.

                command: "/usr/bin/bootstrap_host_exec nova_compute su nova -s /bin/bash -c '/container-config-scripts/pyshim.sh /container-config-scripts/nova_cell_v2_discover_hosts.py'"

In case of updates where we already can have a nova-manage log owned by root make the overcloud deploy to fail with:

We need to fix log owner ship on every deploy run on the computes, like we have on the
controller.

How reproducible:
always

Steps to Reproduce:
1. deploy environment with openstack-tripleo-heat-templates-9.3.1-0.20190314162760.d0a6cb1.el7ost
2. update to openstack-tripleo-heat-templates-9.3.1-0.20190314162762.d0a6cb1
3. run overcloud deploy again

Actual results:
deploy fails on compute with  IOError: [Errno 13] Permission denied: '/var/log/nova/nova-manage.log'

Expected results:
deploy is successful
