Adds an example of proving a mapping file for all nodes, then
extracting the data for each node based on a lookup of the mac address.
Some assumptions are made (e.g the hard-coded reference to eth0), but
it should be easily modified to suit specific environments.
Usage via an enviroment file will look like:
resource_registry:
OS::TripleO::NodeUserData: os-net-config-mappings.yaml
parameter_defaults:
NetConfigDataLookup:
host1:
nic1: "00:c8:7c:e6:f0:2e"
host2:
nic1: "00:18:7d:99:0c:b6"
Note this version requires liberty heat in the undercloud due to the
use of a new str_replace feature to serialize the json parameter.
