Julia Kreger c33f12329c Consider missing MTU invalid metadata
A bug was observed in nova behavior of interacting with ironic where
metadata could be missing in the payload to Ironic. While not great
it is also not awful. In any event, If there happens to be no DHCP
the lack of an MTU can be very problematic and result in a mismatch
between environment configuration and node state.

Fixes an issue where a "null" or missing MTU value for network_data.json
payloads in configuration drives forces a regeneration of the configuration
drive. This behavior is enabled by default, and can be disabled by using the
``[conductor]disable_metadata_mtu_check`` configuration option by setting the
option value to ``True``.
