6bd7eeb7cc
Adds an ansible plug-in that can process the input in THT parameter 'NetConfigDataLookup' used for the OsNetConfigMappings resource in tripleo-heat-templates. Add tasks in the tripleo_network_config role to call the plug-in and write the result into the default mapping file for os-net-config.

- This module creates os-net-config mapping for nodes or node groups based on
|
|
the input data provided. MAC addresses or DMI table strings can be used
|
|
to identify specific nodes or node groups. See manual page for DMIDECODE(8)
|
|
for a list of DMI table strings that can be used.
