-------------------------------------------------------------
Attach an alternative implementation, which localises the patch to the public
host resolution code, not calling out to DNS in the case of a stub provider
spawned instance.
https://issues.apache.org/jira/secure/attachment/12550632/WHIRR-672_VERSION_3.patch
Note although this implementation is cleaner, it does use a private jClouds
API, which could be avoided if we were to expose the Cloud provider at layer
publicly accessible to the org.apache.whirr.Instance, eg
org.jclouds.compute.domain.NodeMetadata.
This implementation also resolves an existing issue, in that it improves the
fallback hostname to include a instance id if DNS fails.

> Allow eager caching of instance hostname based on pre-provision instance
> metadata.
> This would be nice when running the dry run test-harness against services
> which require host name lookups, avoiding long blocking timeouts on DNS with
> nonexistent hostnames, dramatically improving unit test run times.
> It is expected this pre-cache will only be executed by non-production code
> paths, eg unit tests.
