…if the previous ping response has a set master and the current response hasn't. Per single main ping request we maintain the received ping response per node. Each node level ping response is mapped into that. If from a previous node level ping request the response has already been set for a node, it will be overwritten. We give higher value to the latest response. This change makes sure that this doesn't happen if the previous response has a set master and the current response hasn't a set master. Otherwise a node will lose the fact that another node has elected itself as master, the result of that would be that there would multiple master nodes in a single cluster.

…same node elastic#5413 introduced a change where we prefer ping responses containing a master over those who don't. The same change changes the preference of acceptance if both pings have a master indication or if neither do. elastic#7558 added new flag to the PingResponse which changes after a node has joined the cluster for the very first time. Giving preference to older pings cause the wrong value of this flag to be used. This commit restores the preference to the original one.

For unicast zen discovery don't overwrite a ping response for a node if the previous ping response has a set master and the current response hasn't.
