    Introduce oslo config object for adapter_mapping

    This patch introduces a oslo config object for a network adapter port
    mapping. It encapsulates the validation of the config value and does
    the parsing. It's a multi value config option.

    It requires the following arguments

    * name: The name of the config option.

    The config value must be of the following format in the config file

      <name>=<physnet>:<adapter-id>:<port>
      <name>=>physnet>:<adapter-id>:
      <name>=>physnet>:<adapter-id>
      # (multi valued)

    It returns a list of tuples:

      [(<physnet>, <adapter-id>, <port>),
       (<physnet>, <adapter-id>, <port>),
       (<physnet>, <adapter-id>, <port>)]

    where

    * physnet: The physical network string. Can not be 'None'.
                  No restriction in length. Keeps case from config file.
    * adapter-id: The object-id of the adapter that should be used.
                  Cannot be 'None'. Will be returned in lower case.
    * port: The port-element-id string to be used. Defaults to '0'.
                  Cannot be 'None'
