Code Issues Proposed changes

Support per-host overrides of auto_bridge_add 

Support per-host overrides of auto_bridge_add, so we can set different
nic for ovs bridges.
This feature is already merged into openstack-helm. As we don't use
latest version of openstack-helm, so make this as a patch in
stx-upstream.

Subject: [PATCH] Support per-host overrides of auto_bridge_add
.Values.network.auto_bridge_add is a global config. So in multi nodes
deployment, it requires that all hosts have the same nic names. This is
a strict limit.
This patch is to support per-host auto_bridge_add, so that we can define
different auto_bridge_add for hosts.
Also, this patch move .network.auto_bridge_add to .conf.auto_bridge_add
