Subject: [PATCH] Allow to configure service network policy

The patch introduces network policy configuration similar
to openstack-helm services. It allows users to configure
policies depending on the environment.

* Network policies are disabled by default.
* When enabled default policies allow all ingress and
  egress traffic (i.e. policy set to {}), this may be
  changed in future patch-sets.
