Replaces the instance label on prometheus metrics with the inventory
hostname as opposed to the ip address. The ip address is still used as
the target address which means that there is no issue of the hostname
being unresolvable. Can be optionally enabled or set to FQDNs by
changing the prometheus_instance_label variable as mentioned in the
release notes.

CentOS Storage SIG rpms have a recommended install
section that installs podman - let's stop doing that.

Ceph is also suffering from the enormous open files
ulimit that EL9 defaults to - let's set a default
in docker engine for now.

For Masakari and HACluster to work properly, the hostnames used
in HACluster need to match with the hostnames used in Nova.

Hardcoding the first etcd host creates a single point of failure.

Change-Id: I0f83030fcd84ddcdc4bf2226e76605c7cab84cbb

etcd-compatible tooz drivers do not support multiple endpoints via
backend_url. We can put a loadbalancer in front of etcd and configure
backend_url to use the VIP instead. The issue with hard coding the first
host is that we break coordination if we take this host offline. In the
case of cinder, we would not be able to perform any volume related
operations.
