Requests that the machine's persistent hostname be set to the specified value or cleared.

`settings` : | a object implementing `NMSettingsSystemInterface`
`hostname` : | the new persistent hostname to set, or NULL to clear any existing persistent hostname
`callback` : | callback to be called when the hostname operation completes
