GEODE-7926: GMSMemberData is doing unnecessary reverse-DNS lookups (#4894)
Removed hostname lookup from GMSMemberData a serialization method.
InternalDistributedMember does its own hostname lookup & there's no
reason for the lookup in GMSMemberData. I found it was slowing down UDP
communications.

> 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.
