Description

When specifying a UPID like `[e-mail]`, when parsing the string we will resolve `mesos.example.org` and store the resolved IP address in the `address` member of the UPID, while the hostname is discarded.

We should remember that hostname. This will serve two purposes:

• First, we can then display it e.g. in the WebUI or in logs, saving the user from having to reverse the DNS lookup manually
• The hostname can be used for certificate hostname validation when the UPID is remote and we're connecting via TLS to that actor.
