Description

When we send a message via JGroups we write a serialized GMSMemberData in the header of the message. When this is deserialized we are currently using InetAddress.getHostName() to establish a hostname for the new instance. This is costly and unnecessary. We should just use getHostAddress() if we need a hostname in the address data. Geode's InternalDistributedMember doesn't rely on GMSMemberData to establish hostnames for geode-core and other downstream modules.
