  - [PDF] Daisy, Fuel: Drop support for PDF net_config

  - [PDF] zte-pod*: Move net_config to IDF

    Drop 'fixed_ips', which is a leftover from early net_config
    implementation.
    To maintain compatibility with the only 'fixed_ips' consumer (Daisy),
    add 'address' on the first jumpserver interface to leverage Daisy's
    fallback path for determining the gateway.

    While at it, add/update copyright headers.

  - [PDF] bii-pod*: Move net_config to IDF

    Drop 'fixed_ips', which is a leftover from early net_config
    implementation.
    Rework the contents of 'fixed_ips' using the standard PDF spec
    'address' parameter.

  - [PDF] arm-pod*: Move net_config to IDF

    While at it, drop 'fixed_ips', which is a leftover from early
    net_config implementation and is not currently used by the Fuel
    installer (only Daisy seems to use 'fixed_ips', but falls back
    to using 'address' of the first interface when 'fixed_ips' is not
    present).

    Keep 'address: 192.168.11' on jumpserver first interface for Daisy
    compatibility.

  - [PDF] Daisy, Fuel: Add support for IDF net_config

    - support net_config in either of PDF or IDF files;
    - later, we'll remove support for PDF net_config after all PDFs
      have been handled;
