* Change recommended network name to "provisioning" (the default in THT for
the cleaning network) to further emphasize that in real life it should be
a dedicated network.
* Document new IronicCleaningNetwork parameter and its default value
* Update documentation on difference between Newton and Ocata
* Drop provisioning network information, as we don't support this feature yet.
* Drop a note on manually setting cleaning network configuration option.
This is not what we should recommend people do.
