Issue MESOS-3457: Add flag to disable hostname lookup
In testing / buildinging DCOS we've found that we need to set --hostname explicitly on the masters. For our uses IP and `hostname` must always be the same thing. More in general, under certain circumstances, dynamic lookup of {{hostname}}, while successful, provides undesirable results; we would also like, in those circumstances, be able to just set the hostname to the chosen IP address (possibly set via the {{\-\- ip_discovery_command}} method). We suggest adding a {{\-\-no-hostname-lookup}}. Note that we can introduce this flag as {{--hostname-lookup}} with a default to 'true' (which is the current semantics) and that way someone can do {{\-\-no-hostname-lookup}} or {{\-\-hostname-lookup=false}}.
