The ml2_conf.ini has been reformatted to work with the new data type provided from the `provider_networks` module. The new module parses and provides useful information from the `provider_network` list as found within the base user config. The data type has been documented within the defaults so that it can be used in the role as stand alone, outside that of the OSAD project. The module replaces functionality found in top of the ml2_conf.ini file that was built using jinja2 syntax and flow control. The purpose is to allow for more configuration possibilities while also being faster. Closes-Bug: 1434942 Change-Id: If48267ba6f552eaf1535b8ecee6d26b2c6592b31
