[BROOKLYN-579] Add DNS TTL configuration via envvar
Before, java was not refreshing the DNS records, ever. This is due to the
default `networkaddress.cache.ttl` set to `-1`, i.e. cache forever.
This PR updates the system property `sun.net.inetaddr.ttl` to `60` by
default. It uses `sun.net.inetaddr.ttl` because `networkaddress.cache.ttl` **is
not** a system property. But this has the desirable effect (see:
