Promote OSA infrastructure CentOS jobs to non-voting
Promote OSA infrastructure CentOS jobs to non-voting

This patch promotes the infrastructure-related jobs on CentOS 7
in OpenStack-Ansible from experimental to non-voting. The
OpenStack roles are left as experimental for now as they rely
on the infrastructure roles for testing.

There is also a small correction for the os_aodh repo where the
Xenial experimental job was mistakenly moved. This patch also
puts it back in the experimental queue.
